The 140793BC Cat-Back™ system by BORLA® 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 Black Chrome on T-304 stainless steel tip. 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. 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. Ultra-smooth mandrel bends ensure maximum flow & power, and precision CNC manufacturing ensures an accurate fit.
You can count on BORLA® to provide durability, performance, sound, and a Million-Mile Warranty. See separate note about the warranty on tip finish.
