I am about to have my exhaust installed for my 4AGTE but I need to get peoples experience / ideas on which size exhaust to get. I have seen some setups on 1600 tubrocharged cars which have 2.5" systems and they run quite well but also some have 3" systems. Is there any benefit in having 3" as this about $180 more expensive.
Does having a 3" system seem overkill as 2 litre and 3 litre turbo systems use these?
