Exhaust replacement - Toyota Carina E, 2.0L, 1992

resonators can give something and just think the barrel only improves!
and this firmware is for hard tuning ...
for mine, as I heard, it is enough for half an hour - an hour to remove the clip from Akum and the computer is reset ...

I agree. only tuners rewrite the engine control program, change shafts, etc. :) I have a Katalik on my carina, but the resonator and the drum were replaced. So, after the return of the stock parts (resonator and barrel) - the machine became more cheerful ... And so - I myself cannot fully understand this issue - no one can say for sure what depends on what ...

my friend tore off a chisel or a resanator, I don’t know what’s there on our car, and while driving to the medical station she didn’t go at all, did it :)
again, the same person buys an integrator and knocks out the wheelchair and it stops driving normally, I told him I say you make a flame arrester (it will create a delay at least a little) it does and it starts to work fine! :)
and so, there is a rarefaction if you remove some points, then it starts sucking in its own gases, which leads to poor combustion of fuel, it chokes like ...

but, if only the jamming part will be out of the question, I have already consulted, you just scared me :)
but in general such things need to be measured on the dino stand ...
my opinion will not be worse, on the contrary, it is a little easier to breathe! :)
but the catalyst and resonators are already a more serious question ...
because tuners would not change the mufflers for direct-flow just because the car starts yelling, they remove drugs from them,
and our cars are made by engineers for maximum resource and efficiency, because everyone knows that horses are simple so they will not appear, they need to be fed. therefore, the diameters of the pipes are selected there and everything else.
of course it would not be bad to ask a real specialist about this topic, but not so that we are talking here

ugh, that's all :)

Yes, the runoff began to go better. why - I have only one explanation - the engine and exhaust must be matched. After all, for some reason, engineers choose the diameter of the pipe, etc. ... I have heard many different opinions - some began to drive better with the removal of the catalyst and the installation of the glushak, while others were worse ... Most likely it depends on the specific car ...
I observed this: my friend is on Honda punched a muffler - the car stopped driving altogether ... He presses on the gas - she growls but does not go ... I went and welded a hole - started driving ... Although, in theory, a hole in the muffler should facilitate the exhaust exit ...

that is, you want to say that with the stock it began to go better?
in essence, forward flow should, on the contrary, add a little power ...?

Well, whoever likes something :) This constant growling began to strain me. Although, to be honest, I liked the first 3 months :) The most that pinned me was that after the return of the drain, the machine became a little faster and more responsive ... And now the buzz is back - to hear the roar of the engine in the front, and not fart in the back)))))

but I decided to remove the stock on the contrary and put forward flow :)

This is a specifically subjective opinion!
The forward flow should be placed out of the volume of the engine ... preferably the same diameter as the drain pipe! There is a lot of physics!
Therefore, I prefer a sports muffler, not to be confused with a forward flow! It doesn’t growl loudly, and it’s just an optimized muffler by design, not a straight pipe without spitting!

the one that you set will do nothing wrong - EXACTLY

Well, duck all the same, there is nothing bad will not do direct flow ?!
correctly?

The seasoned dvigatelistya knocks everything out anyway ... and cooks the whole issue of pants for themselves! And this is very important and correct! And it's not so easy ... everything must be calculated

that's for sure:)

Here - and I'm about the same. Everything must be accurately calculated. And just cut off the wheelchair and shove it into a Prosport-type can - it could only be worse ...

prosport is generally a hat =)

but here we are not talking about a katalik, but about a can, a forward flow muffler ...

I just gave a prosport as an example :) I had an OBX bank ...

I'm sorry that I'm climbing, minder 1 talked about the reference exhaust pressure and how the engine at the moment of time picks up from the muffler if there is no cans or there is a siphon.
