Installation REQUIRES Cutting Original (O.E.) Equipment Exhaust System. The BORLA® team has developed an awesome sounding exhaust system for the 2005-2019 Nissan Frontier. The 2.5" diameter Cat-Back™ system comes in the S-Type sound level and is specifically tuned for performance and sound on the Frontier’s 4.0L V6 engine. We guarantee that there will be no drone inside the vehicle. Much like the stock exhaust, the BORLA® system features a passenger-side single exit. Its cut-and-clamp installation ensures that the system retains the factory catalytic converters and allows the system to fit both wheelbases available in the Frontier. This system comes with a 4" round bright chrome on T-304 stainless steel tip. A system with a black chrome on T-304 stainless steel tip is also available. The system is manufactured using T-304 stainless steel for increased durability. Bolt on a BORLA® and hear the Frontier roar! All BORLA® Cat-Back™ and Axle-Back systems are made in the USA and are covered by the BORLA® Million-Mile Warranty.
