#1 factory 2 into 1 exhaust pipes; left versus right

Post by HEN3946 » Tue Oct 27, 2020 3:11 am

Hi all; I am restoring my 1971 RHD S3 coupe; I have installed the standard exhaust manifolds (the 3 into 1s) and about to add the lower parts - 2 into 1s. Visually these look identical and I cannot see any identifying numbers on the pieces; however the parts book has these listed as RH and LH. Does any one know a) does it matter if these are reversed b) how can you tell the difference between them if it doe matter? thanks

Hi. I had the same problem after overhauling my engine from my ser 3. I fitted the 2 into 1 down pipes thinking they were the same but when I tried to fit the engine back into the car I found the pipes stood out too far, swapped them round and problem solved. If you loosely fit them you will be able to tell the difference.

thanks for the reply; I installed the 2 into 1's after the engine was installed and they seemed interchangeable. As yet I have not installed a new exhaust system so that might be the moment of truth whether I have lucked out and got them the right way around.
