The 140794BC Cat-Back(tm) system by BORLA(r) is designed to fit Silverado and Sierra 1500 trucks that are NOT equipped from the factory with split rear exit exhaust. It is a side exit system featuring a 4" black chrome on T-304 stainless steel tip and the S-Type sound level. A bright chrome on T-304 stainless steel tip is also available. 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. Add Adapter 60706 for Crew Cab with Standard Bed (6' 7") 157" Wheelbase vehicles. Each system is built from premium, high-quality T-304 austenitic stainless steel, superior to T-400 to give you the absolute best in performance and durability.
