A cat-back exhaust replaces the piping and muffler from the catalytic converter back with dual pipes exiting the rear bumper; this version is cut to match the specific pipe length of a Regular Cab, 8-foot-bed truck (141.5in wheelbase).
why this one — Sized specifically for the Regular Cab 8-foot-bed configuration, so it's the correct-length option for that wheelbase rather than a universal fit.
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. +16dB over stock, +88% flow, -11 lbs per Corsa.
Estimated from comparable claims: MBRP ~+5 whp; Corsa +12; Flowmaster 11; Flowmaster 18
