The aFe Power Mach Force XP turbo downpipes are 100 percent TIG-welded and engineered to perform in the most extreme environments. They use a stepped design that increases exhaust velocity and eliminates low pressure drops—which helps to scavenge the exhaust for increased intake charge and more power. The downpipes are constructed from ceramic coated 3 in. mandrel-bent 409 stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, quicker turbo spool times, and lower EGTs. They're designed using a resonance chamber to reduce the in-cab resonance found with other downpipes. All hardware and brackets are included for a hassle-free installation. Order the downpipes recommended for your vehicle. Additional notes: * Race proven strength and durability * Utilizes the factory mounting locations, providing stability and a direct fit * High-quality OE-style CNC-machined flanges are used for a complete 360 degree sealing surface * Downpipe is ceramic coated inside and out. Developed by the aerospace industry, this coating is used to lower underhood temperatures by insulating the stainless steel tubing. The satin aluminum finish is chip- and heat-resistant up 1,600 degrees F * Available in natural or polished finish
