The Borla 60666 is an optional front resonator used when additional sound reduction is desired on the Volkswagen GTI MK7 and MK7.5 2.0T. It has a 3 inch diameter inlet and outlet and is designed to be used with the Borla Cat-Back systems 140750, 140750BC, 140750SB, 140751, 140751BC, 140751SB, and 140741SB. Adding this resonator to those systems achieves the Touring sound level. It is not designed to be used with 140597 or the original equipment exhaust system. Because it installs behind the factory catalytic converters within a Borla Cat-Back, it is 50-state emissions legal. It is built from premium T-304 stainless steel, superior to T-400 series such as 409, with ultra-smooth mandrel bends for maximum flow and precision CNC manufacturing for an accurate fit. Borla exhaust is handmade in the USA and backed by the Borla Million-Mile Warranty.
