Thanks! (Glad I didn't remove the L99 Resonator... killed most of the rasp and it's still very loud).

I have basically the same setup, just a little different - k&n intake, JBA high flow cats, flow master outlaw cat back. Sounds great

Any video? Wondering how much louder the catback without resonators is?

Sounds Great… Tone isn't much different. My resonator only reduces the higher pitched notes throughout the RPMs; takes off the edge…
