Corona, Ca …advanced FLOW engineering (aFe), an industry leader in performance intakes, filters, manifolds and exhaust systems is pleased to announce the release of their new Mach Force-XP 5” turbo-back exhaust for the 2001-07 GM Duramax with LB7/LLY/LBZ turbo diesel motors part number 49-44007.

49-44007 is constructed out of huge, mandrel bent, 5” 409 stainless steel and utilizes welded-on bayonet style hangers to minimize movement and exhaust wear. A monstrous 5” 409 stainless steel straight through designed muffler is used for an aggressive note and maximum flow. The tubes are held together with OE band-style clamps that provide a leak free seal and a stronger clamping surface than standard U-bolt clamps. All hardware including band style clamps is supplied for an easy installation. This is an off-road only application and the exhaust tip is sold separately.

In recent testing, part number 49-44007 produced 43hp and 112ft. lbs. of torque and improved exhaust flow over the factory exhaust by 178%.

Part Number 49-44007 has an MSRP of $873.75 and is available in stores now.
