Take the sound, pedal response, power and look of your LBZ and turn it up with the Banks exhaust system! The streamlined intermediate pipes and tailpipe are formed of stainless, heavy-wall tubing with constant-diameter bends to maximize airflow and lower exhaust gas temps. The polished-stainless constant-diameter muffler features a straight-through 4-inch diameter flow path with an exclusive expansion chamber to dissipate the annoying mid-range exhaust drone. The monster muffler utilizes spun ceramic, very-high-temperature packing, more than triples stock flow, and delivers an authoritative exhaust sound. An adjustable clamp lets you position it on the tailpipe just right.
