I did a search with no real results, so I thought I would ask the question. With so many using Flowmaster, Walker Dynomax, and others, has anyone here used the Pypes Exhaust 3" catback system and if so, what are your thoughts, likes, dislikes, and quality. How do you like the sound? I have a friend that uses it on a 76 Trans Am that runs dual exhaust but I have yet to find some with a thirdgen. It is the exhasut I am considering when I get my 400 built and put in this spring.
