ExhstSysKt

Introducing the new aFe Power MACH Force XP dual exhaust system for the 05-09 Ford Mustang V6-4.0L. In recent testing, this system produced 12 horsepower and 16 lbs. x ft. of torque. This exhaust is constructed from 2.5in. mandrel bent, stainless steel and is MIG-welded. Dual high flow, stainless steel, single in, single out mufflers are used to maximize performance across the power band while maintaining a great tone. To finish off this exhaust aFe uses dual, laser etched, 3.5in. polished 304 stainless steel tips. Note: The V8 rear bumper cover is recommended (Ford OE Part Number 5R3Z17K835BAA). The use of the OE V6 bumper cover requires cutting and should be performed by a skilled technician.

Product Overview

The aFe Mach Force XP Exhaust System eliminates the use of the restrictive diesel particulate filter (DPF) for maximum performance and extreme mileage gains. This free flowing exhaust system is constructed out of durable 4" mandrel bent 409 stainless steel and uses bayonet style hangers and band clamps for a clean installation. This system comes complete with all tubing, muffler, bayonet hangers, band clamps, thermocouple and pressure tap bungs and is finished off with a high luster polished 304 stainless steel, rolled, slash cut tip.

You will be shocked at the performance and mileage improvement you will see from this system. This system requires the use of a controller with a DPF-delete function. All aFe exhaust systems are engineered and manufactured in our Corona, California manufacturing facility.

*Features*
• Bayonet Hangers - Swaged bayonet ends lock exhaust components into place for the most secure installation possible. Other manufacturers use less expensive bent hangers that allow tubes and parts to slide from side to side, causing premature wear and damage.
• Welded-on Hangers - Every hanger is thoroughly welded on each side to ensure a stronger connection, compared to other manufacturers who use only inferior floating hangers.
• Band Style Clamps - Premium-quality band clamps are used on critical joints to provide the tightest, leak-free seal possible. Other systems use common, less expensive U-bolt clamps.
• Mandrel Bent - All aFe tubing is 100% mandrel-bent. Mandrel bending ensures the tubing maintains its shape and size, providing smooth, unrestricted airflow. Standard tubing can lose as much as 20% of its diameter in sharp bends.

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.

Exhaust System, Mach Force XP, Cat-back, Single In/Dual Out, Stainless Steel, Split Rear Exit, Ford, 4.0L, Kit

aFe Mach Force XP exhaust systems are constructed of mandrel-bent stainless steel and come complete with free-flowing muffler(s), OE-style bayonet hangers, flanges, and band clamps, plus all hardware necessary for a hassle-free installation. Offered in single, dual, or quad muffler configurations, their smooth curves and large diameter tubes help reduce restriction and keep exhaust gas flowing smoothly for increased horsepower and torque.

Available in cat-back, axle-back, and downpipe-back designs, almost all Mach Force XP exhausts are direct bolt-on systems that require no cutting or drilling and include all necessary hardware for a hassle-free installation. Most also include wrinkle-black powdercoated or polished 304 stainless steel tip(s) with a laser-cut stainless steel aFe power badge. Select models have carbon fiber tips with CNC-machined laser-etched inserts.

aFe Mach Force XP exhaust systems are an ideal combination of performance, fit, and value. Additional features include:
• Fit a variety of light trucks and cars, including European models
• Available with 409 or 304 stainless tubing (varies by model)
• "Stepped design" models increase exhaust velocity creating a broader torque curve throughout the rpm range
• Straight-through, free-flowing stainless steel mufflers absorb high-pitch tones producing powerful sound
• Leak-free 360 degree sealing
• Stable pipe location in high-vibration and high-heat conditions
• Bayonet tips hold hanger bushings in place for an OE-style fit
• Several versions convert OE single exhaust to dual exhausts
• Where applicable, incorporates an exhaust valve that uses the OE exhaust valve motor (not included) to regulate exhaust flow
• Some systems use a unique resonance chamber to replace the OE muffler; produces a weight savings of up to 15 lbs.
• Hi-Tuck design of specific models provide extra ground clearance when using an aftermarket suspension kit

Note: Some aFe Mach Force XP systems are "Race Only" products solely for competition use. Their use is limited to closed-course racing that is formally sanctioned by a recognized racing organization. Any other use, including recreational off-road use, could be in violation of local, state, and federal laws.
