Well X pipe arrived, so off with old resonator, found a large section inside had broken away from a sidewall rattling around & possibly could have blocked airflow, so have installed xpipe, sounds good when idling & cruising but put ya foot up it, sounds obscene! Huge cackle from exhaust which I really hate. So anyone out there that has a stock exhaust system lying around (cat back complete in 1 peice)I would be interested in preferably from auto but would look at manual as well, PM me cheers. Or this section below would do, left hand L99 (preferred) LS3 right hand 1, excuse spelling, should check b4 I post
