Scope of delivery: - Downpipe for Audi A3 8v, Seat Leon III, Golf 7 GTI 2.0 TFSI ø 76mm stainless steel with interlock flexible pipe - Clamp ø 76mmDescription: Some modification work may be required; space is particularly tight around the ABS pump.The ø 76mm downpipe significantly reduces back pressure, relieving the turbocharger, which in turn delivers more power and lower exhaust gas temperatures. The post-catalyst sensor may need to be programmed out. The downpipe is made of stainless steel except for the flanges, which are made of steel to prevent distortion and thus leaks. The flange surfaces are machined. Two lambda sensor ports M18x1.5mm are welded in. The connecting pipe to the exhaust has ø 60mm as original. The downpipe is positioned between the turbocharger and the exhaust. A 200-cpi catalytic converter is recommended. It can handle up to 500 hp; of course, the other components such as intake system, exhaust system, injectors, manifold, intercooler, turbocharger must also be installed and the software adapted accordingly.compatible with: - Audi A3 8v 1.8 TFSI FWD 180hp - Audi A3 8v Cabrio 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 (The downpipe must be slightly pressed in at the ABS pump) - VW Golf 7 GTI Clubsport + S 2.0 TFSI 265-310hp CJXE, CJXG (The downpipe must be slightly pressed in at the ABS pump)Not for Quattro modelsRegistration: For individual approval in accordance with §21 StVZO, please contact your TÜV inspector or our partner company Exclusive-Tuningparts e.K. at https://go-street-legal.com/eintragungsformular/Please note that the installation of this item constitutes a modification that will invalidate the vehicle's operating permit under the StVZO.
