eatthis 0 Posted January 11, 2007 iv just bought a cat back jetex system (2nd hand) and to my suprise it has 2 silencers plus the backbox my current system is a backbox and absolutely NOTHING else sounds awesome imo i have a supercharger with 12 psi pulley but it only makes 11 psi (kev made 12.5 psi with this charger) would adding 1 or both silencer recover the lost boost???? i was planning on fitting the big silencer just behind the backbox (suitcase??) but what does the inline silencer do is it good or bad for an fi vr6??
