The 135i 3.5″ Cat-Back exhaust is one of the largest and best-sounding exhaust systems currently on the market. This system is made from top-quality T304 3.5″ diameter stainless steel, features a mid-mounted muffler, and was designed, built, and tested here in the USA. This will fit both the twin-turbo or single turbo 135 applications and an X-Brace spacer can be purchased for an additional amount if desired.
