This Borla system has a valve simulator to prevent the Check Engine Light from coming on. It was designed specifically for the 6.2L Silverado and Sierra 1500. This 2.5" inlet into 2.75" pipes Cat-Back system features a True Dual design which REQUIRES cutting the Original Equipment (O.E) Y-Pipe. The system has the famous S-Type sound level with no drone inside the vehicle. The muffler contains an internal X-Pipe for increased performance and improved sound. This system features dual 3.5" round black chrome on T-304 stainless steel tips on each tail pipe. Installation REQUIRES removal of the O.E. Valance Tips.

Using Borla Stainless Steel Polish p#21499 is NOT recommended with these black chrome tips. We suggest cleaning the tips with hot water and a microfiber cloth. It is built with premium, high-quality austenitic T-304 stainless steel using computer numerical control (CNC) manufacturing techniques that ensures accurate fit and maximum performance. Borla Cat-Back and Axle-Back exhaust systems feature patented straight-through and multi-core technology designed to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive Borla Sound of Power respected by motoring enthusiasts everywhere. Give your Silverado or Sierra the power, performance, and sound it deserves, bolt on a Borla. Best of all, Borla stands behind every system with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.
