CATALYST! removal - Toyota Corolla, 1.8 L, 2003

Another "ulutshaising-uhutschaizing"
has been tormenting me for about a year with the question of removing the catalyst, finally I decided to do it, I don't know if it's good or bad, but I did it anyway!
took off the entire exhaust line, and went with a friend to the service station so that we saw it off and welded the pipe.
to the
service station of a man, I immediately loaded from the doorway, so that everything would be smooth and perfect, not any distortions and attachments (ears) that would also not warp!
This man went into himself for 10 minutes, sat looking, looked at it, etc., in the end I decided to take control into my own hands, suggested how to do that would not distort the whole thing with us, he immediately had a smile and zeal for work (apparently hit him hard).
The work went on, they welded 2 plates for fixing and began to finish the pipe, the cut was successfully sawn off and the new pipe was welded into place, this man turned out to be a good welder, the seams turned out to be neat!

the photo shows that the track has 1 cat and 2 resonators with a
diameter of 61 mm before the cat after a cat, up to 1 resonator 61 mm after 1 resonator and up to 2 resonators 51 mm and so on before the muffler.

sable exhaust pipe =
300r work with a grinder-swerve = 300r
TOTAL = 600r + benz for 15km

thus, the weight of the exhaust route decreased by about 1.5 kg :)
Shl: the cat turned out to be very clean, it shines through very well and does not have any points, spots, etc., to be honest, I immediately got upset ... that perhaps I did this work in vain ...

sensations after 1 pm of driving:
1) the exhaust sound has become a little louder
2) the cut-off in speed is now at 6400 :)
3) maybe a glitch or maybe not, from the bottom (1500 rpm) the thrust and speed set are better than
4) well, it seems like a little quicker, no matter how at least some kind of resistance but there was.

I will remind you about the direct-flow can of the German company FOX

I don't know a lot about it or not, BUT well done! Well done that the old one did not knock out and cut it out carefully. The reverse operation can be done. Good luck!

Rum, therefore, did not knock out, and there were a bunch of such advisers, it is very expensive!
but I have it in good condition, when selling a car I will put it in place, an hour of business and 300-500 rubles
thanks, luck is always needed;)

Abe 15.01.21

Just an egoist who thinks only about his own pleasure ...
=)

yakov 15.01.21

thanks :)
well ... yes, I'm bad :(

Abe 15.01.21

Nature destroyer and greenhouse effect generator! But he did everything neatly ...
It's good that he saved the keg. (^_^)

yakov 15.01.21

ugh ugh ugh, the check does not burn, at a flow rate of 99% that should not increase!

AKA-MANYAK 15.01.21

check did not light up?
my wire somehow came off with a clump, I drove through with the check ...
and when I got under the car I knocked gently on all the banks and it felt like someone knocked out the cat, the owner probably tore off the wire before me ... the
expense would not have increased and the check would not caught fire, and so everything is in akurata

Gizmon 15.01.21

)) I will soon post a photo and video of what I did. Forward flow 60mm, I can't get used to and everyone else too)))

yakov 15.01.21

thanks :) the
muffler is not loud at all, but just for comfort I would like it at least as it was :)
not human, I'll get used to it ... when I just put it on, I went nuts for the first days and then did not notice, you can say so

Gizmon 15.01.21

Not loud!))) Cool sound!

yakov 15.01.21

watch the sound video :)

Gizmon 15.01.21

Well, the waste is clear)) I have 85 and the second year in Russia

yakov 15.01.21

how much mileage?
and I have 60 thousand, and 1 year in Russia in my hands :)

Gizmon 15.01.21

Your exhaust is completely different) is very different from mine.
Katalik is really in excellent condition, I was worse)))

I, too, was a little confused by the field of opening the catalyst, but somehow everything returned to normal later) and now I muddied myself with forward flow.
Shas in reserve, so that people do not frighten people once again, I am looking for a stock issue on 2ЯЯ)

yakov 15.01.21

no question, come in a little later, but I'm going to record right now :)
Shl: what sound I used to also try to lay out or look in B / W earlier (it happened now we growl)

ranler 15.01.21

post a video interesting to listen to

yakov 15.01.21

x h, then I can buy a compressed flame arrester and put it on, or maybe I'll get used to this sound :)

ranler 15.01.21

and my sound became just right

yakov 15.01.21

I am happy with everything and even like it, but it would be quieter ...

ranler 15.01.21

By the way, when I cut out the same effect except for the cutoff offset

yakov 15.01.21

that's it, strangled!
before 2003, this model was 136 hp and after 2003 they began to produce 132, began to look for why hp fell and it turned out what they began to do with reduced emission of harmful substances

somebody 15.01.21

did the right thing. strangled the car)

yakov 15.01.21

I guess how will you do ... pozhze ... compressed flamegas :)

Mikus 15.01.21

woooot, how do you want

yakov 15.01.21

no, I won't, it will be loud!
but I do not like it loud, even one cat pulled out immediately noticeably louder :(

Mikus 15.01.21

handsome
dir all

yakov 15.01.21

stainless steel GOOD, I have 1 more recipe, but alas, I won't tell you yet;)

zizu 15.01.21

I also thought about such prospects, I now have HKS starting with a spider and ending with two cans-resonators, and then such a homemade porn on the 63rd pipe and at the exit a native klushak with entrance 51 :))) and it's hard to find a route to my car, so I think to play with stainless steel chtoli)

yakov 15.01.21

I myself am in shock, the car passed 60 thousand with a penny and it is perfectly clean, everything shines through to the light :)

let's see, in the future there is an idea to weld a completely new track, all 60mm

zizu 15.01.21

The catalyst surprised me for its cleanliness!) I honestly knocked out mine, I didn't think of doing it humanly, but from now on I know how to make it smarter and more environmentally friendly :))

yakov 15.01.21

I thought so too =)

RocketRS 15.01.21

Down with him!)))

yakov 15.01.21

mikh, the sound is good, I agree, only it's a little loud)

corollaz 15.01.21

I liked the sound very beautiful. I envy!

yakov 15.01.21

worth it!;)
everything is OK! but I will get used to the sound, only 2 days I go

gonza-elnik 15.01.21

Yeah. I do not argue the sound is cool, well, tell me now: Was it worth it? =))

yakov 15.01.21

he understood from the moment when I bought the forward flow that it was useless for me to say :)
but if I decide to swap fur or 2zz, then of course he will drop his word and so ... :)
let's see, in winter I can redo the entire track, inside and out!

it is a pity that it is not a mock of a 4-2-1 spider to find on a Corolla with a 1zz motor :(
so at least zvtra redone the
material is, very good but there is no spider anywhere

Yes, I forgot to say, I urgently need a doctor for coding!

ankind 15.01.21

If he finds out, I think he will be shocked =)
Yes, I'm yours, well, not mine =))

yakov 15.01.21

my?
O_O
if yes, then no, I have not seen =)

ankind 15.01.21

Well, here's the point about the folder only, he has already seen this case? =)

yakov 15.01.21

:)) made me laugh, made me happy, but I didn't catch my thoughts :)
PS: I ate sushi with beer ... a lady came by taxi :(

ankind 15.01.21

Vadit, why are you scolding your mother! (C)
=))) The movie "Zhmurki"

yakov 15.01.21

no, I'm not as a deputy, not as :)
thanks of course for the "trust of the country" :)

ankind 15.01.21

In general, Yah, with your ideas, you need to be deputies or immediately replace Medvedev =)
You did everything correctly and competently! I'm just happy for you, honestly!

ranler 15.01.21

beautiful sound

yakov 15.01.21

OK!
answer me on asbestos, I wrote to you in L / S

somebody 15.01.21

please, in the meeting room there is simply no time at all, life is boiling and brains, the heat is terrible. Come in, check out the hood came to me! ::: :)))

yakov 15.01.21

thanks for supporting;)

somebody 15.01.21

the bank is good, but I already wrote about the katalik, well done, I did so

yakov 15.01.21

? up to 20? ugh ugh ugh, it seems to have remained in place, according to the idea it should decrease a little bit

drug1 15.01.21

Thank you, I will buy and do!) The expense did not change after deletion - it jumped sharply to 20 for me. Then I went down to 10

yakov 15.01.21

I wrote above, I bought an exhaust pipe from a sable for 300r, it is not even, but with bends, there is just a piece of the required diameter and length.
so it would be better i think than just knocking it out

drug1 15.01.21

I also knocked out the katalik only did not remove the can - the sound is just tin like a tractor ck)) Did you buy the pipe? Where can I get this piece to put instead of a can?

yakov 15.01.21

thanks buddy :)

DNKaZoT 15.01.21

Not bad ! respect for the movement! :)

yakov 15.01.21

well, eco naturally :)

Jasper24rus 15.01.21

yeah I remember) but live it is probably much better than on the video)

yakov 15.01.21

do you remember which one was before?
now I have become a little bassist =)

Jasper24rus 15.01.21

oooh, what a nice sound and not annoying)

RISOVOD 15.01.21

Because the second bank is not the first resonator, but the second cat =)

yakov 15.01.21

you have 2000 and 136 hp
and I have 2003 and 132 hp

if you carefully study the documentation, you can understand why 4l.s disappeared, after 2003 they began to produce cars with reduced emissions of harmful substances!

PS: it seems to me that I have 2 kata and 1 resonator, today I tapped them and in one a dull sound (full) to another sonorous (empty)

drug1 15.01.21

I have 1 cat 1 resonator)

yakov 15.01.21

Hey. no, we have 1 cat 2 resonator

den-gt 15.01.21

hello buddy, I still don't understand, do we have 2 kataliks?

yakov 15.01.21

holes in the roller?
it is not possible, it will crumble either immediately or after a very short time

den-gt 15.01.21

and if holes are drilled in it, what will be the effect?

yakov 15.01.21

we try, everything should be neat, for ourselves, if not how :)

GEKTOR 15.01.21

The correct decision is that you threw away the catalyst, it is not needed, only the machine is strangling.

Everything is very clean and tidy.

yakov 15.01.21

if all the time briskly and transfer rates are switched, then it is unlikely that the cat.
the cat would choke the car and it would choke it at all revolutions and speeds.
put on 1 gear and unscrew before the cut-off, if it’s briskly, it’s not exactly the cut, you need to go to the diagnostics, and wash the fuel)

corolla-luxel 15.01.21

up to 80 in the city seems to be brisk, but on the highway over 80 is tightly accelerated!

yakov 15.01.21

Hi:)

what are the symptoms?

how to set the speed to 100? playfully or stupidly at all?

corolla-luxel 15.01.21

Hello!
Probox 1.3 problem!
on the highway more than 100 km / h does not go =)
can it be because of the catalyst? (mileage 140,000)
all candles, filters replaced!

yakov 15.01.21

excellent :)
not everything turned out to be so bad

corolla-luxel 15.01.21

flushed the fuel system, the car is going!

yakov 15.01.21

oke :)

corolla-luxel 15.01.21

tomorrow, if there is time, by car we will try to sink to 1 =)
how I will accomplish my goal!

yakov 15.01.21

so try to do as I say! :)
it will 100% show the operation of the pump and kata, if everything is ok then you have to go further ... it's strange of course and all the symptoms are not quite clear, write if something or if the problem is suddenly solved, I will know at least what may be )

corolla-luxel 15.01.21

Okay, we will try in short! =)
maybe something will work out!

yakov 15.01.21

interesting ... how so.
maybe the pump does not give this amount of fuel, but again it is necessary to test, if for 1 gear (L or S) it knocks down and spins up to just then it’s not the pump because at high speeds a lot of fuel is needed and once it spins there is enough fuel!

if this case passes, then we immediately forget the pump and think about something else!

corolla-luxel 15.01.21

and because of the fuel pump will be such crap?
they drove to the diagnostics (did not show it)!

yakov 15.01.21

hello :)
I won't even tell you, it was a long time ago ...
pipe length = kata length =)))

corolla-luxel 15.01.21

Hello!
How long is the pipe for the catalytic converter?
I want a corrugation for the catalyst place =)

JDMwarning 15.01.21

from the bottom (1500 rpm) the thrust became and the set of speed was better, I also began to pull better straight immediately noticed, if I pulled 3000 norms before and now from 1500)) but the sound is hellish screaming

abdulover 15.01.21

yakov

Good day.
Because it is impossible to buy a flame arrester, just order and wait, but as we know, we do not like to wait

I made the flame arrester myself, nothing complicated. In the internet I found a calculation formula, a suitable piece of metal in ferrous metal, made it and welded it instead of kata. I ride for 2-3 years - everything is fine. Even the snag was not needed.

yakov 15.01.21

In order for people to do according to their capabilities!

ingenersbp 15.01.21

sorry ... but I still don't understand why create a record in which everything is beautifully written and do the opposite

yakov 15.01.21

be careful and you will see that the car was sold 4 years ago!
bought a friend and still drives and everything is super

ingenersbp 15.01.21

hmm ... well, 4 years have passed already)) during this time it was possible to wait and do the right thing ... isn't it?

yakov 15.01.21

Good day.
Because it is impossible to buy a flame arrester, just order and wait, but as we know, we do not like to wait

ingenersbp 15.01.21

Hello!
it seems like you write in your article that it is not right to weld a pipe instead of a kata, but did you yourself? what's the catch?))

Amazingmusic 15.01.21

Tell me, where is the lambda probe located? Consumption has not increased? The check has not burned?

yakov 15.01.21

how did you know that it was working? just for diagnosis?
it could fall apart and then pieces get into the resonator and muffler and create sound there

somebody 15.01.21

Can a faulty catalyst go bad. The noise comes from under the bottom like stones in flame carriers. Tell me pliz. Diagnostics did. No errors. W210 3.2

restorator-737 15.01.21

You are not attentive) I did not generalize, but specifically wrote about this case! Do you see the state of the kata in the photo ?! Why cut it out?
What can we say about the fact that in developed countries, no one will let you cut it!

32valves 15.01.21

Talk nonsense.
If the catalyst is clogged, the car will generally not gain high speed.
The stench from the exhaust will only be on a faulty internal combustion engine, there is nothing to do with cat.
About the disturbed thermal balance, neighing)))

restorator-737 15.01.21

Removing the catalyst affects the dynamics like a bully sticker on the trunk lid.
As a consequence, the ringing exhaust, which many perceive as sporty), over time, a stench from the exhaust will appear, and through the disturbed temperature balance of the exhaust system, it will rather die!

HidoOyun 15.01.21

on the contrary, I need to turn off the sound so that it is quiet) apparently I have a hole in the exhaust manifold)))

PaVeL156 15.01.21

Greetings! Didn't find the answer in the comments, I also recently removed the catalysts. The question is about consumption, I have increased from 8.5l by 11l, how was it with you? In fact, I did not measure it, the bortovik writes like this.

FiReeebOy 15.01.21

Is the first resonator like a catalyst also a resonator?

yakov 15.01.21

Thousand 50. No, I did not eat)
Everything is ok

Fantomas123123 15.01.21

Yakov tell me, how many kilometers did you drive after removing the catalyst? Didn't you eat the oil? Has everything tripled?
Thank you!

yakov 15.01.21

judging by the last photo, there is nowhere to screw in front of the flange. is not screwed into the resonator.
did not put everything in the photo

Levis163 15.01.21

If one, then it turns out.
Did you put the flame extinguisher on?

yakov 15.01.21

1 but don't remember before or after, going after it

Levis163 15.01.21

Did you have one sensor in front of the catalyst?

Iugen 15.01.21

And the old one can be sold for how much ... who can help?
