I got mine directly from the manufacturer. I contacted them to inquire about their product and they were very helpful. They sold them to me direct so I could test them out on this application. Pricing runs around $50-60.00 each. Check out the site.

I got the 3032SB. I got these for a couple reasons. As I undersatnd it the larger the inner core diameter, the less restriction. The longer the muffler, the more sound reduction. Also these have 3" inlet and outlet pipes on them. Basicly my plan is to get 4"ID to 3"ID reducers and weld them to the mufflers to construct the insert. I will let you know how it works out. Now if I can only get the sidetubes off!!!
Let me know how the Jet Hot works out. My car had chrome pipes on it when I bought it. I think I would buy the coated ones if I was doing it from scratch. I like the look. How do they hold up on a driver?
