So I did all the reaserach and stuff but still could not get a definite answer..
I was wondering how loud would my G be if i install Crawford Cast plenum and crawford high flow cats.. Anyone?
With an Injen CAI, Kinetix HF cats, and Crawford plenum, my car is noticably louder than stock at 5k+ rpms. It gradually gets louder and louder til 5k or so when it hits it's peak for about 2k more rpm's.
