Corsa's Sport cat-back is built specifically around the Tremor's unique rear bumper cutouts, with dual 4-inch flat-cut tips in polished or black.
why this one — Corsa's own specs claim it's 7.9 dB louder, flows 16% more, and cuts 7 lbs versus stock - and it's engineered specifically for the Tremor's bumper, unlike a generic cat-back that may not fit right.
No manufacturer or independent dyno figure found for this specific product. Cat-backs on turbo trucks with a downpipe/tune doing the real work typically carry no standalone gain claim; sound/tone is the primary value prop. +7.9dB, +16% flow, -7 lbs per Corsa.
Estimated from comparable claims: MBRP ~+5 whp; Corsa +12; Flowmaster 11; Flowmaster 18
