So i bought a used helix catted dp and the cat was bad in it. Im trying to gut it but the cat is right after the belmouth opening. If i dont get it completely gutted will it cause problems? Aaand any suggestions on a more efficient way of gutting the cat than a bent 12" screw driver and a hammer?
Lol i hope it sounds sick. My friend with an 07 impreza 2.5i put a catback on today and its way louder than my rex with a hks hi power. I have no silencer... idk why its so quiet
