Its an F-body three chamber flowmaster. He used some resonated tips as well, not sure what type. It is 2 1/2 " from the cat back, with all mandrel bends.
How do I know... I built it
I agree, it sounds sweet, maybe even better in person. It is by far the best sounding SVT I have heard. I wish it had sounded like that when I had it on my car

I would never have sold it to him if it had. Must have been the crappy pacesetter resonated tips I was using.
You wont get any reply from JVT since he is in europe for a few months.
