RS2 downpipe and cats on 3b engine possible?

[LeoLeandro]

Hi guys.

i'm new there.


fist thing, sorry for my bad english i'm from switzerland and my main speaking language is french .


Actually i'm working on my s2 3b to have a little more power and i've a little question.

it is possible to plug a RS2 downpipe and 2 RS2 cats with the original exhaust of the 3b with out any modification of the exhaust?

or i've to buy a bigger or little middle exhaust to plug this one on my s2 3b?

Thank you in advance for the answer.

best regards.

Don't think so - the 3B exhaust won't mate to the RS2 downpipe and cats from what I can see on the drawings. It may fit if you get an ABY exhaust but I don't know if all the hangars are in the same place.

Sorry I can't be more help!

downpipe is definately different, just found that myself........Mike knows my disappointment, though I am sure he'll benefit from my misfortune

The 3b is a single pipe, then a Y sections bolts the the bottom of the downpipe, whereas the RS2 is cast as a single unit with the two outlets for the cats to bolt up to.

Also the cat shape and pipe dimensions are totally different - definately not compatible with the 3b setup.

Hi.

Thank you for all your answers.

i've contact BN-pipes a little time ago and the society have tell me, The downpipe is only compatible with the RS2 ADU and S2 ABY.
maybee if i put the middle part of the exhaut from a ABY in my 3b this one can be adapted?


Thank you and best regards.

hi leo,

you should take the following parts:

RS2 Downpipe
RS2 or S2 ABY Cats
The RS2 or S2 ABY Sedan / Avant Y-Pipe after the cats

And then you have to connect the Y-Pipe of the RS2 to the Middle-silencer of the S2 3B. This is going to work, you don´t need the middle-silencer of the S2 coupé aby.

If you want to solve it with the S2 ABY Middle-silencer, the way would be this:

RS2 Downpipe
RS2 or S2 ABY Cats
The 2 single pipes after the cats from the S2 ABY Coupe
And the S2 ABY middle silencer

the big advantage with this solution is that it´s plug´n´play, and there is no "Flex" or welding machine necessary. The disadvantage of this solution is that you have to buy a middle silencer and the two pipes after the cats of the s2 aby coupé.

The difference between S2 3b and s2 coupe aby middlesilencer is that there is one single pipe in the s2 3b and there are 2 (!!) pipes from the cats to the middle-silencer in the aby.

concerning the end-silencer i can only say that there is a difference in the part numbers but i can´t see a difference if they are lying in front of me.

Perhaps there had been a change in the end-silencers which cannot be seen from the outside or whatever.

Hopefully this is a help you,
