A 3.0in cat-back exhaust that exits out one side ahead of the rear wheel, with a single 4.0in tip.
why this one — Corsa actually publishes a number for this one (+3 hp / +9 lb-ft, +16% flow) instead of just promising power, and their Sport level is tuned specifically to avoid highway drone - worth it if you tow or commute in the truck.
CLAIMED (manufacturer) - corsaperformance.com publishes 3 horsepower, 9 lb-ft and a 16% increase in flow for this SKU. Small but specific, and it is Corsa's own figure rather than an independent dyno.
