My current set up is American Racing Long Tubes w/ off road x pipe and magnaflow cat back with SLP Tips. I switched tips because I was over sound limits at infineon raceway last time I was there. I wast told double wall tips don't set off the db meter as bad, something about the walls vibrating. I think with my extra 100-170 rwhp I will be way over sound now. I am trying to make it as quiet as possible with out building too much back pressure, I think I am going to try some resonators in front of the mufflers but I don't know if that will help much.

The motor is all stock internally. Basically just a whipple, exhaust and CAI. I switched over to a return fuel system with weldon goodies. We stopped at 7000 rpms and the power was still going up. All the footage in this video was on low boost which made 600rwhp on 15 psi 91 octane. Except the dyno video that was on 19 psi 100 octane
