Axle-Back Exhaust

In testing, the axle-back exhaust system resulted in gains up to +7 horsepower and +10 lbs. x ft. of torque verified by our in-house dyno. Dual free-flowing mufflers are used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque. This axle-back exhaust system incorporates factory style NPP dual mode & AFM (active fuel management) exhaust valves which use the factory exhaust valve motors (not included). The valves helps regulate, direct and control the flow of exhaust gases by opening, closing, or partially obstructing passageways depending on throttle position for maximum performance.This MACH Force-Xp axle-back exhaust system uses factory mounting locations providing stability and a hassle-free installation. Finishing off this system are quad light weight, 4"diameter carbon fiber tips. The tips feature an aFe POWER logo which give an aggressive yet elegant sporty look. High quality band clamps are used for a complete 360 degree sealing surface. The performance axle-back exhaust system is constructed of 3" mandrel-bent, brushed 304 stainless steel tubing for maximum performance, corrosion resistance and strength eliminating cracking. Failures of original equipment AFM and NPP actuators are not covered by aFe POWER's warranty

Important Notice relating to US Domestic Market Trucks & Pickups

Many US-market trucks and pickups are available in multiple cab and bed-length configurations (e.g., Single Cab, Extended Cab, Double/Crew Cab, CrewMax, 5.5ft/6.5ft/8ft beds, etc.). Exhaust system fitment can vary between these chassis versions.

Where available, we list all compatible vehicles, cab types, and bed lengths in the product description. However, depending on your exact configuration, some systems may require optional extension/mid-pipes or minor modification for correct fitment.

Because of these variations, please carefully check your cab configuration and bed length before purchasing. If you are unsure, or if your vehicle has been modified, please reach out to a StreetFX agent.
