The Gibson single-side cat-back exhaust for 1999–2000 Chevrolet K2500 (7.4L) enhances low-end torque and acceleration to improve towing and passing performance. Dyno-tested gains typically range 10–15 hp and 15–20 lb‑ft from 1800–3000 rpm. The stainless mandrel-bent system pairs a baffled Superflow muffler with a polished slash-cut tip and factory-style hangers for a straightforward no-weld bolt-on install, quieter cabin sound and lifetime limited warranty coverage.
