Milltek Sport Cat-Back Exhaust - 2016+ Audi TT Mk3 TTRS 2.5TFSI Quattro

Upgrade the Audi TT Mk3 TTRS 2.5TFSI Quattro (2016+) with a Milltek Sport cat-back exhaust. Milltek builds each system around the car it fits: mandrel-bent T304L stainless pipework, a larger bore than stock for freer flow, and a tuned sound you choose, from quiet and refined to loud and uncorked.

Sound options

• Resonated options keep cruising drone down and sound closer to a refined sports car.
• Non-resonated (louder / race) options give the loudest, rawest note. Better for track days and weekend cars than daily commuting.

Choose your setup

• Sound: the system type and sound level.
• Tip Finish: the tailpipe trim.
• Optional Downpipe: add a Milltek catted or catless downpipe built to fit this cat-back. Pick Cat-Back Only to skip it.
