Bull-X downpipes 2.75" Audi S6/RS6, S7/RS7 C7/4G, S8 4H 4.0 TFSI (HGDPAU01M)

BULL-X Exhausts produces downpipes at the highest level. These Bull-X downpipes can be swapped 1:1 for the original parts. Perfect fit and high-quality materials make these items a top product in our range. Optimising the diameter, the pipe routing and the catalytic converters greatly reduces the load on the turbochargers. The lower back pressure produces a clear gain in torque, power and earlier response, while at the same time extending durability thanks to the reduced thermal load. Plug & play solution - perfect fit, simply swaps for the original component high-quality materials one-piece cast outlet flange to ensure maximum flow optimisation Made in Germany - genuine quality from our own production flow-optimised and performance-enhancing improved durability and response optimum evacuation of exhaust gases - no disruptive edges at the transitions designed and tested on the computer and on the dyno 70mm pipe diameter incl. adapter to the factory system not approved under the StVZO Notes: 1. As the original front pipes cross over, the lambda sensors must be fitted crosswise after these downpipes have been installed (the sensor routed from the left to the right downpipe and the sensor routed from the right to the left downpipe) 2. Does not fit if an Akrapovic system is installed, as it uses different front silencers! This item is not approved for use on public roads - For racing purposes only! CAUTION! All catalytic converters/cat replacement pipes offered, except the EC-tested catalytic converter from HJS, are not approved under the German road traffic regulations! Only with the EC catalytic converter may you legally drive your vehicle on public roads. The use of all other catalytic converters is intended for racing purposes only. If, despite our notice, you fit a downpipe with a catalytic converter WITHOUT EC approval, you are committing a criminal offence. Possible consequences include: invalidation of the operating licence, decommissioning of the vehicle, a complaint for tax evasion, and possible investigations by the environmental authority.
