Unitronic UH027-EXA Downpipe and High Flow Cat Audi and VW 2.0T AWD
The Unitronic UH027-EXA Downpipe replaces the restrictive factory downpipe with a larger, 76mm stainless steel mandrel-bent system, featuring a high-flow catalyst,V-band clamps, and various other features. Expect better throttle response and significant power gains, all while remaining civilized during normal daily driving.
The Unitronic downpipe features a smooth 80mm to 76mm turbo to downpipe transition designed to maximize flow and minimize turbulence. This transition then feeds into the 76mm T304 Mandrel bent stainless steel tubing to a 200 cell metal matrix catalytic converter in the OEM position to ensure quick warm up. After the HFC an O2 sensor bung is placed in the OEM position to allow installation without wiring modification. An 8" flex section is welded in after the O2 sensor to account for engine movement under hard throttle. From there a v-band flange is used to attach to the midpipe which then terminates in another v-band which can attach to an aftermarket exhaust or into the included 76mm to 65mm adapter to allow connection of the OEM catback if needed.
