A cat-back exhaust replaces the piping and muffler from the catalytic converter back. Corsa's dB Series is a reverse-flow muffler design meant to sound loud outside the truck while staying quieter and less droning inside the cabin at highway speed.
why this one — Corsa's Sport line with a single 4-inch tip uses their dB Series muffler to cut interior drone while keeping an aggressive exterior tone.
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. Corsa publishes flow%/weight instead: +9% flow, -6 lbs.
Estimated from comparable claims: MBRP ~+5 whp; Corsa +12; Flowmaster 11; Flowmaster 18
