We are proud to release our first new product for the TTRS 8S / RS3 8V facelift 2.5TFSI. Iroz Motorsport's High Flow Downpipe features a CNC machined 4″ T303 stainless steel v-band flange and turbo outlet. Our 3″ mandrel-bent stainless steel design is free of obstructions and uses a premium core interlock style flex section. For optimal clearance between downpipe and driveshaft, our design splits from a 3″design to a dual 2.5″ design where two more stainless steel flanges mate seamlessly to your secondary catalysts or high flow mid pipes. Our Secondary Pipes are required if you do not want to custom build mid pipes. Each downpipe is hand built in our facility, and test fitted in our handmade jigs to ensure exact fitment each and every time. We back purge each pipe to ensure our lifetime warranty is never used. In addition to the quality craftsmanship and great sound, our TTRS High Flow Downpipes come with installation hardware.
These products are for offroad use only. Our experience with the OEM calibration is that o2 extenders do eliminate the CEL. For race cars on the stock calibration, we can advise what has worked well for us. The proper solution is modifying the OEM calibration to eliminate the secondary o2.
Unleash the sound of the 2.5TFSI with these pieces, where gains of 27whp on 91 octane have been seen on several beta cars.
Installation time is 3 hours and a lift is highly recommended. The OEM downpipe is the opposite of fun to remove. We recommend the driveshaft removal tool from Audi to remove the stub mount on transfer case as well. We will have our own tool available to purchase shortly.
Highly recommended is the Driveshaft Removal Tool 8S/8V Facelift. If your shop does not already have one, it will save a significant amount of labor.
