MagnaFlow is pleased to announce cat back system #16726 dual rear exit for the 2006-07 5.3L V8 Grand Prix, GXP. The system features 100% full stainless 2.5" piping, resonator, dual mufflers in the rear complete with a set of 3.5" mirror finish stainless tips.
It features full mandrel bends (no compression bends, like those done at muffler shops) for maximum flow and a straight through, wide open muffler with NO baffles, NO chambers and NO restrictions.
The system installs with simple hand tools and in most cases, can be installed by the average do-it-yourselfer in 30-60 minutes.
Installation Instructions:
