Fits models with Original Equipment (O.E.) Single Tail Pipe ONLY. The 3" into dual 2.25" diameter BORLA® Cat-Back™ system has 2 full tail pipes with a single 4" round black chrome on T-304 stainless steel tips 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. A system with bright chrome on T-304 stainless steel tips is also available. It has the mellow Touring sound with no drone inside the vehicle.
