Today, aFe announced the release of their new, 3-inch-diameter, Mach Force-XP after-cat exhaust for '09 Chevy Silverado and GMC Sierra trucks equipped with the 4.8L, 5.3L, or 6.0L V-8 engines.
Mach Force-XP exhaust systems are constructed out of 409 stainless steel and utilize welded-on, bayonet-style hangers for a complete installation that won't shift under high heat or vibration conditions. A 409 stainless steel straight-through-designed muffler is used for an aggressive note and maximum flow. The system also features a monster 4-inch-diameter stainless steel welded-on tip. All hardware, including band-style clamps, is supplied for an easy installation.
The folks at aFe say that recent testing produced 12hp and 14 lb-ft of torque and improved exhaust flow by 28 percent when compared to the stock exhaust.
The exhaust system has an MSRP of $582.35 and is available in stores now.
