Bull-X Exhausts produces exhaust systems and downpipes at the highest level. Like these 2.25" Bull-X front silencer replacement pipes for the Audi S4 B9 and S5 B9 exhaust system. Converting back to the original front silencers is possible. - Material: stainless steel - replaces the front silencer - no approval - Pipe diameter: 2.25"/60mm Under “Video” you will find the matching sound file for this item. Note: for the conversion/removal, the original front silencer pipes must be separated or cut while still fitted to the car. Removal is therefore not done in one piece (see example image). As a result, fitting costs are very low. As the perfect complement to the front silencer replacement pipes, we recommend the Bull-X Tronic Valve Control. With this control unit you can operate the valves of your OEM exhaust system manually. If desired, both valves of your S4/S5 B9 exhaust system also open when stationary, which is not possible in stock form and noticeably intensifies the sound.

The replacement pipe offered is not approved under the German road traffic regulations (StVO)! Only with an ECE exhaust system and 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.
