The JBA cat-back exhaust for 2001–2006 Chevrolet and GMC Silverado/Sierra 2500 HD (6.0/8.1L) is a 409 stainless steel passenger-side dual-exit system built for improved flow and sound. It combines mandrel-bent large-diameter tubing, high-flow mufflers, polished chrome tips, quality hardware and factory-style hangers to replace restrictive stock piping and provide a tuned, robust exhaust tone.
