To extend this system to fit the longer Double (Crew) Cab With Long Bed (6' 1") 140.6" Wheelbase models use adapter 60593. This 2.5" diameter Borla Cat-Back system features a 4" round black chrome on T-304 stainless steel tip. 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. The system delivers the classic S-Type sound with no drone inside the vehicle.
