Product Description

The Gibson 612201 cat-back exhaust is Gibson's flagship performance system for the early 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 409 stainless steel mandrel-bent tubing and finished with a polished 304 stainless steel slant-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, it's a well-rounded upgrade for Frontier 2.4L owners wanting more usable power alongside a genuinely aggressive sound.
