The best improvement to my truck so far. Pacesetter Quik Trip Long Tubes really woke up my 2003 GMC 5.3 Sierra 1500. I installed the optional Off Raod Y-pipe. Had to do a custom tune with my Diablo Predator, (also purchased at Auto Anything) to clear and eliminate the O2 codes. Just the weight savings of stripping off the old manifolds and Y helped out the truck, but the power thatn these help suck out of the engine, is awesome. Would I buy them again compared to Pacesetters competitors? Yep... Buy them!
