Monster® Exhaust
ISB PICKUP: Constant-diameter to slash backpressure and lower exhaust gas temperatures, Banks' Monster exhaust pipes bolt behind the turbocharger. The streamlined 4" turbine outlet pipe, head pipe, intermediate pipe and tailpipe are formed of stainless, heavy-wall tubing with constant-diameter bends to outflow stock and the competition. Banks replaces the factory's restrictive muffler with a polished-stainless Monster muffler, featuring a straight-through 4"-diameter flow-path with a Banks-designed expansion chamber to dissipate the annoying mid-range exhaust drone that plagues most straight-through mufflers. Muffler utilizes spun ceramic, very-high-temperature packing and delivers an authoritative—but never intrusive—exhaust sound. The huge 5" polished-stainless steel tailpipe tip sports a rolled edge. Double-walled design with 1/2" air gap keeps heat from tarnishing exterior mirror finish. Adjustable clamp for positioning on tailpipe. Extension pipe included for extended-cabs.

Accolades
“The word "engineering" is very important here because Banks is not just reselling someone else’s products. They have full time in-house engineers and technicians, performing their own research and development on every different type of performance option you can imagine.”
