Our good friends at Advance Flow Engineering (or aFe, in wheeler-speak), an industry leader in performance intakes, filters, manifolds and exhaust systems, has released the new Mach Force-XP 3-inch cat-back exhaust for the 2007-08 Chevrolet & GMC Suburban, Yukon, Avalanche, and Tahoe with V-8 4.8L, 5.3L, or 6.0L gas or flexfuel motors.
Mach Force-XP exhaust systems are constructed out of big honkin' mandrel-bent 3-inch 409 stainless steel and utilizes 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, and a gigunda 4-inch stainless welded-on tip finishes the exhaust. All hardware is supplied for an easy installation. In recent testing, the exhaust was said to produce an extra 12 hp and 14 ft-lb of torque while improving exhaust flow over the factory exhaust by 28 percent. How awesome is that?
