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 a classic head-turning sound, we recommend our S-type sound level. It provides a significant difference in tone 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.
