The Gibson single cat-back exhaust for 1997–1999 Chevrolet S10 ZR2 (4.3L) is a stainless single-side system that exits behind the rear tire to improve acceleration, towing and low-end torque. Dyno testing shows strong gains in the 1800–3000 RPM range with typical 10–15 horsepower and 15–20 lb‑ft torque gains. It installs bolt-on with included hardware, keeps cabin noise restrained, and is backed by a Lifetime Limited Warranty.
