The prochamber was $265 and the catback w/ 3.5 SS tips was $370. Not too bad.
Fitment with the prochamber, no problem. The fitment with the catback, well...that took some time to get everything just right along with some custom grinding on the exhaust tip brackets. They wouldnt fit in the housings that are welded to the tips, had to grind the outsides to make them thin enough to fit. The catback tucks up nice and tight; tighter than the SLP. NO LEAKS whatsoever. Awesome sealment.
