Description
A restrictive factory exhaust system limits your 6.0L or 8.1L GM truck’s breathing potential and traps backpressure that kills horsepower. This JBA cat-back system removes that constraint with mandrel-bent 3-inch piping and 3.5-inch polished tips, delivering measurable gains in power output and a purposeful exhaust note. Whether you’re towing heavy loads or pushing peak performance, a properly engineered exhaust is the foundation of any serious engine upgrade.
