Alright so i've done some searching on the subject and i found a few things but not much. I put my header on last weekend, its the rksport 4-2-1, after fixing the leaks (about a week later that was fun lol) I have found that it is really loud now, it is kinda raspy and i just wanted to know if anyone had some clips of their exhaust running about the same setup with a cat back. I am probably going to invest in a resonator. However i think i may still have a small leak somewhere. Also i was wondering if some of you with the rk have had a similar experience. Any opinion or enlightenment on the subject would be appreciated.

I have the rksport 4-2-1 with high flow cat and a free flow exhaust muffler. I took it to the exhaust shop to be put on . No problems. very satified..
