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.
