EXCEPT ZR2 & AT4X models. Factory Split Rear Exit vehicles ONLY. This system features a black chrome finish on T-304 stainless steel tips. Using BORLA(r) 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. This Cat-Back(tm) system by BORLA(r) is unique in the industry. It features a "True Dual" design which requires cutting the factory Y-Pipe. The system has the famous BORLA(r) "S-Type" sound level. The muffler contains an internal H-Pipe for increased performance and improved sound. 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. Best of all, BORLA(r) 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.
