Fits Audi RS3 and TTRS with DAZA engine codes only

034 Motorsport is proud to unveil the all-new Cast Stainless Steel Performance Downpipe for Audi 8S TTRS and 8V.5 RS3 models equipped with awesome 2.5 TFSI EVO DAZA engine! Offering increased horsepower and torque throughout the powerband, reduced turbocharger lag, and an enhanced exhaust note, this is the ultimate downpipe solution for the discerning Audi enthusiast.

Optimized for increased flow and maximum performance, the Cast Stainless Steel Performance Downpipe for the Audi 8S TTRS and 8V.5 RS3 features organic geometry and a massive 150mm diameter Euro 4 200 cell racing catalytic converter in the factory location. The dual downpipes have a diameter of 70mm, 17% larger than the OEM 60mm diameter downpipes,  This complete downpipe solution includes an integrated v-band flange at the turbine outlet, integrated oxygen sensor bung after the catalyst, OEM-style corrugated flex bellow, and factory-location exhaust hanger. The 2.5 TFSI EVO DAZA Cast Stainless Steel Performance Downpipe is constructed from 304 stainless steel and TIG-welded for maximum durability and corrosion resistance.

034 Motorsport's 2.5 TFSI EVO DAZA Cast Stainless Steel Downpipe was developed entirely in-house on 034Motorsport's Development 8V.5 RS3 and 8S TTRS utilizing the latest in 3D Scanning Technology, CAD Software, and Rapid Prototyping Techniques. Final production units were then tested extensively on multiple enthusiast-owned vehicles before release.

We recommend this downpipe is installed with Audi RS3 ECU tune from 034 Motorsport. This is to make use of the increased exhaust flow the ECU should be recalibrated. Stage 2 with appropriate mods can produce +178 BHP!

      Excellent product high quality.
      Size: 36 sqft, Size: 36 sqft
      This stuff definitely suprised how easy it was to work with. Not to mention it sticks very well. Don't put it on anything you may need to get back into. It will take the paint off of a service area. I have a 2018 dodge durango. I just had a aftermarket audio sytem installed. It was rattling so bad it was driving me crazy. I seen this stuff and decided to give it a try. Its a night and day difference no moore rattling. I box will be enough to do my back gate and all front and rear doors also. For the price you honestly can not beat it. If your on the fence about trying it don't be. You definitely won't regret getting it. Its worth every penny. You don't realize how much something rattling in your vehicle robs you of spund quality. Glad I made the decision. Now off to the other 4 doors. ,and then the roof. One of the things I really like was the fact it has multiple line to help you make even better cuts. Definitely will buy a gen.

      Affordable, Clean and does the job.
      Size: 36 sqft, Size: 36 sqft
      I consumed about 90% of this box doing all doors and the tailgate on a 2000 tahoe. I applied it very liberally inside every door (exteror) panel. We then added an almost equal amount of deadening/absorbing/decoupling foam to the other side of the door (panel side). If you know how many rattles a circa 2000 tahoe GMT800 can have by now, you can appreciate why I added this as a "must" if i were to put some money back into this vehicle. Best sub $150 spent on this mini resto so far, right next to tint. Good quality. Not to thick or thin. Good sized sheets. Seamed to deaden as good as another slightly thicker material i recently used in my F250. My box was delivered with no issues of melting or anything funky. Clean, no major smell before or after and easy to work with. Maybe buy a roller set and wear gloves. Save your hands if your doing inside of panels. Good buy. Will buy more for future projects.

      AS GOOD AS ANY OTHER, WORKS GREAT
      Size: 36 sqft, Size: 36 sqft
      Used this in my 17 RAM 1500. This stuff works great, just as good as S...ss brand that is also sold on here. Same thickness and same tackiness. And this stuff sticks like crazy, once its laid down and rolled onto the surface, it is hard to remove, so I am pretty sure it will stay where I installed it. It is great value, one box was enough to do the whole roof of the truck with a little left over for small spots. I think it took a total of 2.5 boxes to do my whole crew cab, roof, floor and back wall and most of the firewall, and I also added a layer of their .25" foam. I do notice a difference in less outside noise, from wind and road. I will be doing my wife car soon, and this is the product I will be using again, I recommend this.

      Dyna... who?
      Size: 36 sqft
      This stuff works great. Fraction of the cost to Dyna.. and just as good. Very sticky. Used in doors, floors and ceiling. Great product and performs flawlessly. I would highly recommend this.
