Product Description

The Gibson 12211 cat-back exhaust is Gibson's flagship performance system for the Nissan Frontier, designed specifically to boost torque and horsepower in the low-to-mid RPM range where trucks do most of their towing, hauling, and daily driving. Its Superflow muffler uses a baffled and chambered internal design rather than packing material, delivering an aggressive exterior tone while keeping interior drone to a minimum on long highway drives.

Built from aluminized mandrel-bent tubing and finished with a polished T304 stainless steel slash-cut tip, this system installs as a straightforward bolt-on using factory-style hangers - no welding or cutting required. With average gains of 10-15 hp and 15-20 lb-ft of torque, plus reported fuel economy improvements when paired with other bolt-on mods, it's a well-rounded upgrade for Frontier owners wanting more usable power alongside a genuinely aggressive sound.
