Corsa Performance Sport 3" Cat-Back Exhaust, 147.5" Wheelbase (6.2L V8)

A cat-back exhaust system replaces everything from the catalytic converter back - resonator, muffler, and tailpipes - while leaving the factory manifolds and catalytic converters in place. It is a bolt-on install that mainly changes exhaust sound with a modest, real airflow gain.

why this one — Corsa's own site states a specific, real claimed gain (+17 hp/+16 lb-ft) for this exact 6.2L Silverado/Sierra system rather than a vague "improves flow" pitch, and it is sold direct through Corsa's approved affiliate program (Corsa Direct) so a purchase here can actually be tracked.
