Flowmaster's American Thunder cat-back for 2021-2026 trucks, dual 2.5-inch tailpipes with polished tips.

why this one — Flowmaster's own dyno testing claims up to 11 hp and 10 lb-ft at the rear wheels - there's no independent dyno backing that number up, so treat it as the manufacturer's number, not a verified one.
