The Borla team has developed an awesome sounding exhaust system for the 2005-2019 Nissan Frontier. The 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. 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 particular system (140802BC) comes with a black chrome on T-304 stainless steel tip, but is also available in bright chrome on T-304 stainless steel (140802). Using Borla Stainless Steel Polish p# 21461 is NOT recommended with these black chrome tips. We suggest cleaning the tips with hot water and a microfiber cloth. As one would expect, the system is drone-free and constructed using T-304 stainless steel for increased durability. Bolt on a Borla and hear the Frontier roar! Borla exhaust systems are covered under our Million-Mile warranty with the following exceptions. Borla will warranty black coatings, tip finishes, and carbon fiber parts for one year.
