Borla 140797BC 14-18 Silv/Sierra C/B Exh ATAK 1500 5.3L V8 Ext Cab(78.7) Crew Cab(69.3) 143.5 WB Black Chrome

This 2.75” diameter into dual 2.25” BORLA® Cat-Back™ system is tuned for sound and performance specifically for the 5.3L engine in the Silverado and Sierra 1500. For the vehicle owner who is looking for an aggressive and head-turning sound, we recommend our ATAK® sound level. It provides a drastic difference in tone and overall volume from the much quieter stock exhaust system while maintaining a drone-free driving experience in the vehicle. This system has a dual side exit with single 4" round rolled edge tips in a black chrome finish on T-304 stainless steel on each tail pipe. Using 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. Easy bolt-on installation.

BORLA® Cat-Back™ & Axle-Back exhaust systems feature patented straight-through and multi-core technology to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive BORLA® Sound of Power respected by motoring enthusiasts everywhere

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 numerical control (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 warranty on tip finish.
