Are you talking about an LS1 car to begin with, and is it turbocharged? Need more info. 2.5" total size exhaust is fine up to a certain extent on a rear mount, if that answers your question.

Sorry no this is a european engine i couldnt find anyone else to help. I have an audi 200 20 valve turbo. from the header it splits to 2 2inch pipes going to separate cats then 2 2inch mid pipes run back to a resonator and a muffler which continue to carry 2 2inch pipes. i want to eliminate the resonator and muffler by putting a Y pipe at the end of the pipes making the 2 2inch to one 2 1/2 inch straight back about 3 feet.
