The CTS Turbo 4″ high-flow downpipe for the Audi TTRS and RS3 with the 2.5T engine features a CNC-machined 4″ T304 stainless steel V-band flange and turbocharger outlet.
It is made from mandrel-bent 4″-diameter stainless steel, without restrictions or flow obstructions. It uses a high-quality flexible element with an interlock design. For optimum clearance between the downpipe and prop shaft, the 4″ pipe splits into two 2.5″-diameter pipes. At their ends are additional stainless steel flanges for connection to secondary catalytic converters or high-flow centre pipes.
Suitable software for adapting the engine electronics is required to prevent the Check Engine warning light from coming on. The downpipe is compatible with Stage 2 software from any brand.
