Exhaust Q


My Car's Too Loud...
I was wondering what would be the best size exhaust for my carbed TR motor. I want to run a single pipe, for simplicity purposes. Is 3 1/2" too big? Or would 3" be right?

I think that 3" would be just right IMHO. When you start getting above that it's hard to bend the pipe without resticting the pipe.
I would also agree , 3" is plenty. Jack Cotton has 3" cat back exhaust systems for around $300.00.
I remember a debate in the General Tech forum about which was better, daul 2 1/2" or a single 3". I think the consensus was that both were big enough to pose no restriction.
