After going actual stage 2 today, having done the stage 2 washer mod the night before, the growl is MUCH louder with just the cobb HFC now. It sounds awsome. All my friends love it, and this was just what i was looking for. I've been wanting an exhaust to hear the car for the longest time, but couldn't justify spending 700-1000$ for a sound upgrade.
Thanks for the awsome mod info Hog!
