Its a bone stock D23 with F2 header and the FSWerks "steath" exhaust. But the "steath" resonator was replaced with a striaght pipe. The only thing left in the exhaust is the muffler just ahead of the rear subframe.

SCCA takes noise levels at NHMS, the limit there is 99db, I was hitting values between 94 & 97 db. I think the meter was on the infield side of the main straight so they get your engine at full throttle.
