aFe is proud to introduce the MACH Force-Xp dual side-exit cat-back exhaust system for the 2014-2019 GM Silverado/Sierra 1500 with V6-4.3L/V8-5.3L engines. This cat-back exhaust system is constructed out of 3" 100% MIG-welded, mandrel-bent, stainless steel tubing for maximum flow. The smooth transition bends allow for low turbulence, increasing horsepower, torque and improving throttle response. In testing, this system resulted in gains up to +14 horsepower and +17 lbs. x ft. of torque verified by our in house dyno (vehicle tested 5.3L engine). A hi-flow 21" single-in dual out muffler is included which improves performance across the power band while maintaining an awesome sound. This unit uses all factory mounting locations and comes with a bolt-on bracket that supports the driver side tailpipe. The aFe power dual side exit exhaust system was designed to retain the spare tire and includes high quality band clamps and OE-style bayonet hangers. This makes for an easy installation with no cutting required. To finish off the exhaust, are massive dual 4-1/2" high-luster polished stainless steel tips with a laser-cut stainless steel aFe POWER badges for an aggressive style.

Installation is a Snap:
This MACH Force-Xp exhaust system uses all factory mounting locations and is supplied with all necessary hardware including OE style hangers for the perfect fit and finish.

Aggressive Sound:
A free-flowing stainless steel muffler is used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque out of your rig.

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.

Leak-Free Seal:
High quality OE-style flange and band clamps are used for a complete 360-degree sealing surface eliminating leak paths.This exhaust system fits perfectly without removing the spare tire.

Flow and Performance:
MACH Force XP exhaust systems are constructed of 3" mandrel bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and improving throttle response.

Massive 4-1/2" Polished Tips:
Finishing off the exhaust are dual high-luster polished stainless steel exhaust tips. The tips feature unique stainless steel laser-cut aFe Power logo plates which are riveted on for an aggressive style.
