MTC Motorsport Audi TTRS 2017+ Stainless Steel Decat Downpipe & Mid Sections The TTRS downpipe and mid pipes are machined from SS304 aircraft-grade stainless steel and are tig welded in houseThe downpipe is 4” straight out of the turbo and 2.5” when it splits into 2 which provides a sharper throttle response due to faster spool of the turbo.Provides noticeable power gains and a much more aggressive exhaust note which sounds truly amazing. Feedback from customers is that the downpipe crackles and bangs but is quiet on the motorway which is perfect.It produces lower temperatures and less exhaust backpressure due to the relief of the turbocharger. The cylinder charge is increased meaning you get maximum performance.There is also a substantial weight saving in comparison to the factory catalytic converter.The decat is mandrel-bent for better gas flow and maximum internal size to ensure ultimate performance without the loss of mid-range torque.Finished in brushed stainlessWe have tested this product and found increases of around 25-30bhp on test vehicles however, it does have the capability of increasing horsepower by 120-150bhp once your car has a stage 2 map.Will fit the following models perfectly: Audi TTRS 8S 2017+Audi RS3 8V 2017+ Professional installation is recommended as some exhausts sit slightly different from others.
