This MACH Force XP Cat-Back exhaust system is constructed of 3" into to 3-1/2" mandrel-bent stainless steel tubing and comes complete with a free-flowing muffler, OE-style bayonet hangers, band clamps, and all hardware necessary for a hassle-free installation. The smooth curves and increased diameter of this exhaust system help remove restriction and keeps exhaust gas flowing smoothly for increased horsepower and torque. In testing, this system produced +35 horsepower and +39 lbs. x ft. of torque over the stock exhaust system verified by our in-house dyno. The system is finished off with a side exit 4-1/2" wrinkle black 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:
A high quality OE-style flange and premium 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.

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:
This MACH Force XP exhaust system is designed with a 3" to 3-1/2" stepped design which increases exhaust velocity and creates a broader torque curve throughout the RPM range.

This exhaust fits the 157" wheelbase ONLY.

Emissions Disclaimer:
This product does not require a CARB EO# (CARB Aftermarket Parts Verification Guidelines).

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

Sounds great!
Hardest part of the whole job is getting the 8 year old bolts unfrozen. Looks great, sounds great way more responsive. I also installed a new intake system and throttle body spacer. Couldn't be happier.
