Here's my setup...

JDM ITR motor, stage 2 Skunk2 cams and cam gears, DC 4-1 headers w/ 2.5" collector, short ram intake, Carsound hi-flow cat, Trust piping, ES 2.5" muffler, and Mugen ECU chip.

What could I do to reduce noise/sound? I'm really concerned as I feel I'll get pulled over every other block. I could be exaggerating but it's pretty loud. What can I do to make it sound almost stock? Should I start by putting stock ITR cams in or headers?
