A cat-back exhaust replaces the piping and muffler from the catalytic converter back; this is Corsa's Sport 3.0in dual rear-exit system with factory-style bezels for the 5.3L V8, 147in wheelbase trucks.
why this one — Corsa backs this one with a real dyno claim (+17 hp / +15 lb-ft) rather than just a sound upgrade, and keeps the factory-look bezels instead of aftermarket tips.
