A cat-back exhaust replaces everything from the catalytic converter back to the tips. It changes sound and sheds a little weight - it is not a serious power mod on its own.
why this one — SPD does not publish a power figure for this system - the HX Series is their single-exit configuration for the 14th-gen truck, bought for sound and looks rather than a dyno gain.
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.
Estimated from comparable claims: MBRP ~+5 whp; Corsa +12; Flowmaster 11; Flowmaster 18
