The flange surfaces are machined. Two lambda sensor connections M18x1.5mm are welded in. The connecting pipe to the exhaust has ø 60mm as original. The downpipe sits between the turbocharger and exhaust. A 200 cell cat is recommended. Power up to max. 500hp can be run, of course the other components such as intake, exhaust system, injectors, manifold, intercooler, turbocharger also need to be installed and software adapted accordingly.Suitable for: - Audi S3 8V 2.0 TFSI (Convertible, 3-door, Sedan and Sportback) Quattro 300hp + 310hp - Seat Leon III 5F 2.0 TFSI Cupra 300 ST All-Wheel Drive 300hp engine code: CJXC - VW Golf 7 R 2.0 TFSI 4-Motion 300-310hp CJXG, DJHAOnly for All-Wheel Drive, 4-Motion and Quattro modelsRegistration: For individual approval in accordance with §21 StVZO, please contact your TÜV tester.Please note that the installation of this item constitutes a modification that renders the vehicle’s operating permit under the StVZO void.
