Scope of delivery: - Downpipe for Audi A3 8v, Seat Leon III, Golf 7 GTI 2.0 TFSI ø 76mm stainless steel with interlock flex pipe - Clamp ø 76mmDescription: Adjustment work may be required, especially at the ABS pump it becomes a bit tighter.Through the ø 76mm downpipe, the back pressure is significantly reduced, the turbo is relieved which in turn brings more power and lower exhaust gas temperature. The post-cat sensor may have to be programmed out. The downpipe is made of stainless steel except for the flanges, which are made of steel so that they do not warp and thus prevent leaks. The flange surfaces are faced. There are 2 oxygen sensor connections M18x1.5mm welded in. The connecting pipe to the exhaust has ø 60mm as original. The downpipe sits between the turbocharger and the exhaust. A 200 cell catalytic converter is recommended. An output of up to max. 500HP can be achieved, of course the other components such as intake, exhaust system, injectors, manifold, intercooler, turbocharger must be installed and the software adapted accordingly.suitable for: - Audi A3 8v 1.8 TFSI FWD 180HP - Audi A3 8v Cabriolet 1.8 TFSI FWD 180HP - Audi A3 8v Sportback 1.8 TFSI FWD 180HP - Seat Leon III 5F Cupra ST 2.0 TFSI FWD 265,280 and 290HP - Seat Leon III 5F 1.8 TSI 180HP CJSA, CJSB - Skoda Octavia III 5E 1.8 TSI 180HP CJSA - Skoda Octavia III 5E RS 2.0 TSI 220-230HP - VW Golf 7 GTI 2.0 TFSI FWD 220-230HP CHHB, CHHA - VW Golf 7 GTI Performance 2.0 TFSI 245HP CHHA DLBA (With the ABS pump, the downpipe must be pressed in slightly) - VW Golf 7 GTI Clubsport + S 2.0 TFSI 265-310HP CJXE, CJXG (With the ABS pump, the downpipe must be pressed in slightly)Not for Quattro modelsRegistration: For individual approval according to §21 StVZO, please ask your TÜV inspector or our partner company Exclusive-Tuningparts e.K. at https://go-street-legal.com/eintragungsformular/We would like to point out that the installation of this item constitutes a modification that causes the vehicle's operating license to expire according to the StVZO.
