From the engine, the exhaust flows through our 1- stainless tubing which includes O2 bungs to accommodate both stock and 18mm sensors. From here the exhaust steps up to 1 and 7/8 before dumping into the spring retained collector for increased torque. The exhaust then emerges from the collector into our 4 Touring muffler to deliver an unparalleled sound upon exit.
Features:

• Designed to deliver maximum torque
• Race-inspired stainless steel headers shave pounds off the competition to ensure a long lasting, weather-resistant, amazing sounding exhaust
