Corsa Performance Sport Cat-Back, Single 4" Tip (dB Series)

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.
