Innovative Banks Power 48629 4" Single Monster Exhaust System Bonkers Deal: 45% Off [8Uxlkyo3]

Banks 4" Monster exhaust system flows up to 176% better than stock and cuts back-pressure up to 98%. Constant-diameter to maximize flow and lower exhaust gas temperatures, the Monster exhaust pipes bolt behind the turbine outlet pipe. The streamlined head pipe assembly (non-cat.-converter equipped vehicles only), intermediate pipe(s) and tailpipe are formed of stainless, heavy-wall tubing for rugged durability.

The polished-stainless Monster muffler features a straight-through 4"-diameter flow-path with an exclusive expansion chamber to dissipate the annoying mid-range exhaust drone. Monster muffler utilizes spun ceramic, very-high-temperature packing, more than triples stock flow, and delivers an authoritative exhaust sound. 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.
