MACH Force-Xp 3 IN 409 Stainless Steel Cat-Back Exhaust System

GM Silverado/Sierra 1500 09-19 V8-5.3L
(Fits Crew Cab & Ext Cab Models)
Part Number: 49-44038-B

aFe introduces the MACH Force XP exhaust system for the 2014-2019 GM Silverado/Sierra 1500 V8-5.3L with the 143.5" and 153" wheelbases. This cat-back is constructed using 3" mandrel-bent 409 stainless steel and uses a free-flowing muffler. OE-style bayonet hangers and band clamps provide a stable pipe location during high vibration and heat conditions. The smooth curves and increased diameter of the exhaust system helps remove horsepower robbing restriction and keeps exhaust gas flowing smoothly for increased horsepower and torque. The system is finished off with a black powder-coated 304 stainless steel, rolled slash-cut tip for an aggressive style.

Installation is a Snap:
This MACH Force XP uses all factory mounting locations providing stability and a hassle-free installation.

Leak-Free Seal:
High quality OE-style flange and band clamps are used for a complete 360-degree sealing surface eliminating leak paths.

Aggressive Sound:
A straight-through designed, 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.

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.

Fitment Note:
This item will only fit Extended Cab/Short Bed (143.5"Wheelbase), Crew Cab/Short Bed (143.5" Wheelbase), & Crew Cab/Long Bed (153.5"Wheelbase) models.

Emissions Disclaimer:
This product does not require a CARB EO#

All aFe exhaust systems are engineered and manufactured in our Corona, California facility.

Buy it, you’ll thank yourself later.
It took me longer to get the stock exhaust system out! Installation was a breeze. Everything was straight forward, simple, and very well crafted. The end result is a deep low end grumble at idle, and throaty notes throughout the rpms. It’s quiet inside the cab, no drone, just enough to let you know it’s there. I wish it had a little more volume, but that’s attainable with headers and a y pipe. I already have the Stage 2 cold air intake with the Pro 5r filter and the Silver Bullet throttlebody spacer. Pretty happy with everything so far!
