What is interesting is that this catback is pretty much the best flowing catback you can have in 3". It looks like a clone of the tsp rumbler/slp loudmouth style. Imagine the gain over a catback with a muffler that is not straight through.

Wow, nice gains! I have a similar catback to you with the same bullit muffler. Without the headers and highflow cats, I wonder if I would still see a decent gain?

Thanx again for the thread, I almost started my own until i searched. Now because you opted for the tune for the street (closed) do you think it will effect performance when you open it..? Meaning any real gain? Track times for example..
