Gibson cat-back single exhaust for 1998–2000 Ford F-150 4.2L provides a stainless, single-side exit designed to improve low-end torque and throttle response. Dyno results indicate horsepower gains across the low RPM band with quieter in-cab noise than many other systems. The baffled SuperFlow muffler reduces interior drone while polished slash-cut tips, mandrel-bent tubing, factory-style hangers and included hardware make for a hassle-free bolt-on installation with a lifetime limited warranty.
