A true 5" from the down-pipe back, the new Large Bore-HD exhaust is engineered to perform in the most extreme environments. This system is constructed from mandrel bent 5" stainless steel tubing for maximum flow, increased horsepower, increased torque and lower EGT's. The 2-piece tailpipe and bayonet style hangers provide a hassle-free installation. To provide a leak-free seal, OE style band clamps are used that offer a 360-degree sealing area. A 30" free-flowing straight-through designed muffler is used to produce a deep, powerful sound.
