hi

just some questions i got a rear sports muffler a while ago i was looking at the piping and the piping going into the rear muffler is smaller than the rear muffler i dont know what to do is it worth while getting 2 half inch piping all the way and getting a performance catilac converter and some extractors would that make it louder prices would be good to.

from what i have been told dont worry about the cat, get the 2.5" though, resi and muffler, will sound nice, extractors arent really necessary if you just want the sound, they will add some sound and a bit more of a gain. with pricing, you could get a cat back system for about $380 $400ish, depending on rear muffler. extractors.....$660 supplied for RPW race design, and i think pacemakers are about 400 supplied...youll need them fitted though, the RPW ones are a straight bolt on if yoy have the 3.5ltr, otherwise youll need them fitted too
