Bull-X Exhausts produces exhaust systems and Downpipes at the highest level.

Like these Bull-X pre silencer replacement pipes for the Audi S4 B9 and S5 B9 exhaust system.

A retrofit to the OEM pre-silencer is always possible through the supplied material.

Attention: The original pre-silencer pipes have to be cut for removal when installed. The removal can´t be done in complete condition (see example picture). As a result, the installation costs are very low.

We recommend the Bull-X Tronic Valve Control as the optimal complement to the pre silencer replacement pipes.
With this control you can manually control the valves of your OEM exhaust system. If desired, both flaps of your S4/S5 B9 exhaust system can also be opened while standing, which is not possible in series production, and which significantly enhances the sound image.
