Aggressive Sound:
A muffler delete-pipe is used for a true race-inspired sound and maximum flow.

Perfect Fit:
OE style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The Bayonet tip holds the hanger bushing in place for an OE style fit that does not change with time.

Flow and Performance:
MACH Force XP exhaust systems are constructed of 5"" mandrel bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT’s.

I went back and forth on whether or not to do a 4" or 5", and am I glad I went with this 5". It sounds amazing, was a simple install and looks great! High quality band clamps and a simple install made this a no brainer. Not too loud, unless you want it to be, no drone and excellent V8 rumble. I also like the turn on the tailpipe giving it a little bit of an older Chevy look with the straighter outlet. 06 LBZ CCSB
