Description

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 the OE cat-back only. It does not fit Milltek cat-back systems. The equivalent downpipe for Milltek cat-back systems is SSXAU582. 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.
