Thunderfunk
Ready to race!
I am stage 2, I just got it without the testpipe file. I also want to add that while under heavy throttle I notice a loud air turbulence sound coming from towards the rear. At first I thought it was a rattle but the more I listen it does not sound metallic. It doesn't matter what RPMs or speed I am at, just when I lay on the pedal. Is this just added noise from the downpipe with stock catback or something else?
