A cat-back exhaust replaces the piping and muffler from the catalytic converter back to change sound and improve flow; this version exits out the side of the truck rather than the rear bumper.
why this one — A Roush-branded side-exit cat-back built for first-gen (2011-2014) 3.5L trucks, giving the factory-style Roush look and fitment rather than an aftermarket-only brand.
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
