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 with 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" black stainless steel tips with a laser-cut stainless steel aFe power badges for an aggressive style. This kit retains your spare tire and includes high quality band clamps and OE-style bayonet hangers for a hassle-free installation.

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.

Retains The Spare Tire:
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" Black Tips:
Finishing off the exhaust are dual black stainless steel exhaust tips. The tips feature unique stainless steel laser-cut aFe Power logo plates which are riveted on for an aggressive style.

    Chris B. (Philadelphia, Pennsylvania, United States)
    Definitely love it

    This definitely a great fit from the look to the performance. Would recommend it for a clean look in the engine bay

    Great product

    Good quality for money

    Only gripe is they are a little longer than i’d want but they work like a charm. No need for heat shields on your spark plugs wires.

    Where is it?

    I never got that order. My new address is 18 Tides Edge Place, Sacramento, CA 95835

    Exactly as described

    Exactly what i needed. I'm so glad these guys could explain the difference in the pad material compared to the 3 other places I called. Will be back soon.

    Toyo® Proxes R888R DOT Competition Tire
    Scargod (New Haven, Connecticut, United States)
    Noisy and not sticky enough when pushed

    I have run quite a few Hoosier R7's but wanted the size available in the 888R's for my new BRZ. For one thing, I had forgotten how noisy they are! I could live with that if they performed better on a dry track.
    When pushed hard for 20+ minutes they eventually build up enough heat to start getting greasy and losing grip.
    For many they will be adequate for track days, but I drive my cars too close to the limit. A better tire for me in the dry has been the Eagle Supercar F1 3R's.

    Haven't received them yet

    As above

    Not a fit

    Unfortunately the belt did not fit, it was was too long, my fruend had a 2018 SRT, he had the same problem with his order.
    The transaction process was easy, the belt seems like good quality, too bad it didn't fit
