Scope of delivery: - Downpipe ø 76mm stainless steel for Golf 4 R32 Turbo stainless steelProduct description: The ø 76mm downpipe significantly reduces backpressure, relieving the turbocharger which in turn delivers more power, torque and lower exhaust temperatures. The post-cat sensor may need to be programmed out. The downpipe is made of stainless steel except for the flanges, which are made of steel so they do not warp and thus prevent leaks.An M18x1.5mm lambda sensor connection and a clamp fitting for the exhaust temperature sensor are welded in. The downpipe sits between the turbocharger and the catalytic converter, it was fitted directly to the vehicle and is designed for a catalytic converter (not as in the original with two). A 200 cell cat is recommended. It can run up to max. 550hp.Compatible with: - Golf 4 R32 Turbo only in combination with the following parts:Turbo manifold http://www.turbo-parts.de/Turbo kr uemmer-Turbo-Kruemmer/Audi/VW/Turbokruemmer-R32-V6-Golf-4-S3-Nicke lg uss-T3-T4-Flansch-38mm-S2-Turbo-Kruemmer-geschlitzt::1910.html or http://www.turbo-parts.de/Turbokruemmer-Turb o- Kruemmer/Audi/VW/Turbokruemmer-R32-V6-Golf-4-geschlitzt-ausgeglueh t- geplant-und-sandgestrahlt::1536.htmlTurbos e.g. Garrett GT3076R GTX3076R, GT3582R, GTX3582R with the exhaust housing htt p: //www.turbo-parts.de/Turbolader/Ersatzteile/Abgasgehaeuse-Garrett- 82 -A-R-for-GT3582R-with-internal-wastegate::887.html + this flange http://www.turbo-parts.de/Flansche/Flansche-am-Turbo/Flansch-fuer-Hosenrohr-fuer-GT3076R-GT3582R-Edelstahl-GT30-GT35::1017.html + V-band ring http://www.turbo-parts.de/Flansche/Flansche-V-Band-u-Auspuff/Anschweissring-aus-Edelstahl-95%3E76mm::2615.html which must be welded onRegistration: For individual approval in accordance with §21 StVZO, please ask your TÜV inspector.Please note that the installation of this item constitutes a modification by which the operating permit for the vehicle expires according to StVZO.
