This 2.5" diameter 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 Borla "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. BORLAUsing 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. All this without the annoying drone often associated with performance exhaust systems. Give your Silverado or Sierra the 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.
