I would but it wouldn't pass inspection cuz pa ia passing a knew law about exhaust has to be stock. So with the offroad y-pipe with a cat on it would look stock and im replacing the resonator with a glasspack so it resmbles a resonator and im upgrading from 21/4 to 21/2 exhaust pipe.

Thanx for the info.....
