Corsa Performance Sport Cat-Back, Dual Rear Exit (Reg Cab 8ft, 141.5" WB)

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.
