On this beautiful 2012 Audi TT-RS we installed a Milltek catback sport exhaust, as well as a Milltek downpipe, this really gives the car a awesome sound (to hear the difference between a stock TT-RS and the one we did check out the video posted below). Once the exhaust was fully insatalled we upgraded the ECU with the stage 1 ECU upgrade from APR to give the car more power while still maintaining the ride from a factory TT-RS. To top it off we tinted all the windows to give it that blacked out look which suites the car very well.
