Forward flow … how to register … in winter! — Toyota Sprinter, 1.6 liter, 1994

Hello.
Let me tell you a story that hasn't ended yet.

means what we have.
a Toyota Sprinter car with a 4a engine (my brainchild), after the purchase.

so, well, my eyes lit up. and for 1 day he was already with me (and this is my mistake), + the catalyst was cut out and a straight pipe was welded in there, that is, Artyomka had no obstacles. for exhaust gases, in the car NOT IT WAS)).

approached 30 days from the purchase of a car. well, I'm a law-abiding citizen … and I'm going to get registered.

Here I come to Khilokskaya 9. to the place of reconciliation of numbers. Everything is fine, the numbers match (well, how else can it be))), and then he goes around the car from behind ... (he went there 2 times with Mark, and 1 time with Corolla, they never went to look in the ass) and says:
Oh, shaitan pipe ... go nice to the PTO ...
and writes on the application (150 rubles ruined ... bastard) NOISE, well, what can I do ... food means ... let's skip the little things., then two of them come up. one in gray ... and in uniform, the other employee of the VAZ service center ... and shout:
start ... gasp ...
Well, I let off a little gas ...
how would I explain to you what Apexi N1 is ... in short, the one in uniform already jumped. well, they waving their hands and say you for a hundred. and writes to me on the statement: Inconsistent.

upset by this. on this day I took whiskey, cola ... although that's another story.

okay, so I went to the masters to make a silencer.
done.
I'm going straight to the PTO with the same statement.
Again, the procedure is repeated only THIS time! it was not me who gasped, but a service employee ... and the microphone was brought right next to the pipe ... I looked at the sound level meter ...: 104 dB blew out from me with a plug.

pretty much getting on my nerves. with the help of friends, there is such a thing
www.6pl.ru/gost/Gr52231-2004.htm
for those who are too lazy to open the link, I will explain, this is
GOST R 52231-2004 External noise of vehicles in operation. Acceptable levels and methods of measurement
in which there are a lot of "HOLES" with which ... these guys can't check anything at all.
let's go through the points:

— ambient air temperature from minus 10 °С to plus 30 °С;
- atmospheric air pressure - from 92 to 105 kPa;
— relative air humidity — no more than 80%.

5.2.4 The pavement of the test site shall be asphalt concrete or cement concrete, dry, smooth and clean, with a minimum dimension of 10 x 10 m.

5.4.1.2 Place the microphone at a distance of 0.5 m from the exit pipe

5.4.1.3. The main axis of the microphone shall be parallel to the surface of the platform with a deviation of no more than ±10° and make an angle of 45°±10° with the vertical plane passing through the axis of the flow of exhaust gases leaving the muffler exhaust pipe.

some excerpts from...

let them at least provide a platform with an ambient temperature! ..

Well, I also got a little safer)) I put something in the pipe ... what is she whispering to me right now.

What is all this for, because you can say that people are doing their job, and poking GOSTs in their faces will not be beautiful ...
no ...

and there is also documentation that indicates that the State body does not have the right. send to the PTO when checking the numbers ... in other words, they are obliged to register the car ... and whether the vehicle is subject to operation or not, it will be decided at the MOT ...

here)) tomorrow I’m going with these pieces of paper))) let them clean the site and warm the air))))
