The Nissan Frontier is a capable truck in both utility and sport; whether you are using your Nissan Frontier for fun or work, the addition of a STILLEN 2.5 inch Cat-Back Exhaust System will help your truck deliver the performance you demand.

Dual Exhaust Construction

STILLEN went through a strict regimen of design, engineering and testing to ensure the STILLEN 2.5 Cat Back Exhaust for the Nissan Frontier delivered performance where you could feel and use it best. STILLEN tested 2, 2.25 and 2.5 tubing to ensure the most power gains across the meat of the power-band.

Single Muffler Design

The dual mandrel bent 2.5 inch exhaust tubing construction continues all the way to a single muffler. Then exits through a single 3 inch exhaust pipe that finishes with an aggressive black tip with red STILLEN logo. This cat back exhaust is equipped with our signature STILLEN muffler producing the aggressive sound you hear under throttle.

4" Engraved Tip

The powerful muffler has been paired up with a 4 inch Black Exhaust Tip that has been engraved with our signature STILLEN branding for authenticity and style.
