The 4 inch intermediate pipe and tailpipes are formed of stainless heavy-wall tubing with mandrel bends to maximize airflow, minimize backpressure and lower exhaust gas temperatures. The system safely clears the spare tire, shocks and brake lines. Monster singles include a 5 inch round tip span(with your choice of high temp Black or chrome-over stainless). Adjustable clamp for positioning on tailpipe. (And to help keep the tips looking good, there's a 1/2 inch air gap to keep heat from tarnishing the finish). Banks Monster Exhaust for the 6.7L is available in the following configurations (not all configurations are available for all year ranges).
