Milltek Large Bore Downpipe & Cat For MK3 Audi TTS (Non OPF/GPF) - To Milltek Catback

Must be fitted with the Milltek Sport cat-back system and requires a Stage 2 ECU remap

Milltek Large Bore Downpipe with 200-CPSI hi-flow sports catalyst for the Audi TT Mk3 TTS 2.0TFSI Quattro, 2015 to 2018, non-OPF/GPF models. This downpipe fits Milltek cat-back systems only. It does not fit the OE cat-back. The equivalent downpipe for the OE cat-back is SSXAU585.

76.20mm (3.0") mandrel-bent T304L stainless steel with hand-finished welds and CNC-formed flanges. The large-bore section cuts backpressure and improves scavenging against the restrictive OEM downpipe. The 200-CPSI hi-flow sports catalyst is the EC-approved grade in the TTS downpipe range and flows substantially better than the restrictive factory unit. Stage 2 ECU remap required to realize the gains.
