Lighter system offers more flow and makes more top-end power than the factory system. Feature 1-3/4" 16-gauge mandrel bent, interconnected headers and 220° full-coverage heat shields. Front pipe crosses over to the left side and is securely mounted to the transmission oil pan. Crossover pipe is formed from the 1-7/8" tubing for increased ground clearance and no cross-sectional area loss. Hidden inter-connect for maximum top-end horsepower, improved low-end torque and sound dampening. Includes (2) 18mm O2 sensor ports, plugs and all mounting hardware. Accepts any '95-'16 OEM-style dresser mufflers (sold separately). O2 sensor ports and plugs, gaskets and all mounting hardware included. Made in the U.S.A..
