Our Cat-Back Systems were designed with two goals in mind; to produce more horsepower and keep them affordable. We begin with fully aluminized 16-gauge tubing and use a proven mandrel bending process to form a smooth flowing system that is free of any "ripples" or "kinks" which restrict and slow exhaust flow. Then we add high flow turbo style mufflers for a throaty sound and increased flow while keeping the system emissions legal. Kits include adjustable hangers, clamps and hardware. Easy bolt on installation. Made in the USA.
