I got my dynomax cat back system in the mail yesterday so I put it on thinking it was going to be a quiet exhaust. But after I had tighten everything down and doudled checked I started the car and wow what a difference My exhaust has a v8 tone and is loud. So I decided on monday I am going to get a custom made y pipe to get rid of the t pipe that is on there. And later knock out the cat and put a pipe going through that. So it will not only pass inspection but it will be high performance exhaust. I have a couple of recording of the before and after exhaust and after each mod I will do a different recording to hear the difference. If you guys have any other Idea for the exhaust please post them.

 

maybe some 60' times if you can, then you could tell if it made a good performance distance.
