Audi TTRS Catless Downpipe & Link Pipes Audi TTRS Catless Downpipe & Link Pipes Description Audi TTRS Catless Downpipe & Link Pipes Fitted with an incredible 2.5L Straight 5 engine, the TTRS is a true sleeper. But like many turbo cars the stock downpipe is a choke point, and opening it up can allow additional power and faster turbo spool. VelocityAP's Audi TTRS Downpipe replaces both the factory downpipe as well as the secondary catalytic converters, retaining the OEM mounting to the rear exhaust section. It will mate up to any factory or aftermarket exhaust that uses the stock mounting points. Our downpipe tapers from 3.5" down to 3" before mating to the stock exhaust, and is targeted at those who want moderate power gains, but without the sacrifices in mid-range & low end torque that come with large diameter setups designed for huge power increases. Manufactured entirely from aeronautical 304 grade austenitic stainless steel Tig Welded & Purged throughout Fully mandrel bent and backed by our 25-year guarantee against corrosion and workmanship. Utilizes original mounting points, no fabrication required to install FITS ALL AUDI TTRS MODEL YEARS   Click image to enlarge Images sell!
