Milltek Sport Downpipes - 2016-2018 Audi TTS Mk3

These Milltek Sport parts fit the 2016-2018 Audi TTS coupe (Mk3, 8S) with the 2.0 liter turbo four. These 76 mm large-bore Milltek downpipes for the Mk3 TTS come with a 200-cell HJS cat, a hi-flow sports cat, a 200-cell race cat or no cat, each made to join either the factory or a Milltek cat-back. A Milltek hot-side part replaces the restrictive factory section with larger, smoother T304L tubing, so exhaust gas leaves the engine with less resistance. Pick a catted version to keep a catalytic converter in the system, or a catless version for a dedicated track car. Each option below says whether it joins the factory cat-back or a Milltek cat-back. The Audi TTS Mk3 parts are T304L stainless steel with mandrel-bent tubing, which keeps the pipe at full size through each bend and resists corrosion for years. They bolt in place of the factory parts with no cutting or welding.

• Factory Cat-Back versions join your original exhaust; Milltek Cat-Back versions join the Milltek TTS cat-back. Each one includes a connecting pipe.
• Milltek lists the HJS and race-cat downpipes as race products; the hi-flow sports cat version is not a race product. All of them need an ECU remap, and the catless versions are for off-road or track use only.
• Catless parts remove the catalytic converter. They are sold for off-road and competition use only and are not legal on public roads in the US.
