Borla 140797BC ATAK Cat-Back Exhaust System for 2014-2018 Silverado and Sierra 1500 5.3L V8

The Borla(r) 140797BC ATAK(r) Cat-Back(tm) is tuned for sound and performance specifically for the 5.3L engine in the Silverado and Sierra 1500. For the owner who is looking for an aggressive and head-turning sound, we recommend our ATAK(r) system. It provides a drastic difference in tone and overall volume from the much quieter stock exhaust system while maintaining a drone-free driving experience inside the vehicle. This Cat-Back(tm) system features a dual side exit with round rolled tips in a black chrome finish on T-304 stainless steel and bolts on to the factory exhaust for ease of installation. Using Borla(r) 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. Each system is built from premium, high-quality T-304 austenitic stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer-controlled CNC manufacturing ensures an accurate fit. You can count on Borla(r) to provide durability, performance, sound, and a Million-Mile Warranty. See separate note about warranty on tip finish.

Do not use Borla Stainless Steel Polish, part number 21499, on the black chrome tips; clean them with hot water and a microfiber cloth instead.
