Re: aveo exhoust 2""
i think the muffler is the most restrictive part of the exhaust, so i would start on that end if you are not doing the whole thing.
then when you have more money replace the middle pipe.

yeah i would wait myself and do the whole thing at the same time, im going to buy another set of headers and run 2.25 or 2.5 pipe to a high flow muffler, nothing in between

its february already?
Re: aveo exhoust 2""
The most restricted part is the header. Its way too small and short before it merge. It gave me the biggest power increase before I did anything to the engine.
I would say 2 inch is too big.
I am using 2 inch straight through last time. Even with 155hp and 201Nm I find it ok only. Any RPM below 2.5k is a pain. Too draggy. You need to keep rpm high constantly for better response.
Now I am using 2 inch straight thru with a straight thru muffler in between, and a 2 inch semi flow rear muffler (due to noise, my local cops like to catch illegal exhaust, and each time is a hefty near $600US fine). ANything other than original is illegal. If we want legal one such as fujitsubo or N1, super sprint, remus...etc it will cost abt $1000US+ including the certificate to certifity its approved by the authority. Its all about tax. That cert cost $800+US. The muffler only cost $200+US.

Re: aveo exhoust 2""
The only thing on the exhaust that I see changing is the header, just because I like a quiet car, and leaving everything else. But I also like power... but then again who doesn't?
