On a 2002 GTP, how would this compare to the SLP Loudmouth system....Dynomax super turbo mufflers, U-bend replacement, and 2 1/2 inch pipes, should I use a Catco or Dynomax cat convertor? Also, is the stock pipe on the GTP crinkle pipe? and what size is it...2 1/4?
Well i have a 99 gtp and i just installed a high flow cat converter and a borla cat back and i would never go back here is a link of grand prix stuff copy both lines one after the other
I removed the resonator, replaced U-bend with straight pipe, installed high flow cat, and installed Flowmaster 40 series....loud as hell...more than the Borlas :O)
