Large 76mm stainless steel downpipe with racing catalytic converter for all 2.0 TFSI and TSI such as in the Audi TT(S), A3, S3 and VW Golf 6 and many more. This high-quality stainless steel downpipe has a diameter of 3". The connection for the exhaust system is tapered so that the original exhaust system also fits the downpipe. The racing catalytic converter is a 200 cell metal catalytic converter which again significantly reduces the exhaust back pressure. The downpipe is mounted directly at the outlet of the turbocharger and guides the exhaust gases to the catalytic converter. The larger the diameter of the downpipe, the better for the engine's power delivery. The exhaust back pressure is thus reduced and the service life of the turbocharger is positively influenced. The main advantages: 89mm before catalytic converter Largest possible pipe routing Elimination of the pre-cat 200cpi racing catalytic converter Interlock flex pipe Significant increase in performance Much faster acceleration of the engine Lower exhaust temperatures and exhaust back pressure Longer service life of the turbo and engine (No approval, registration possibly by individual approval) (Image similar) Manufacturer Information about the manufacturer BAR-TEK BAR-TEK Motorsport GmbH Im Rauschen Auel 3, 51491 Overath-Brombach, Germany info@bar-tek.com
