BULL-X //  Sport Exhaust System "EGO-X" with valve for BMW 335i F3X


BULL-X is an exhaust brand created by HG-Motorsport, specializing in the "Hot Hatch" preparation in Germany.

Their experience of almost 20 years in this area has made it possible to develop stainless steel sport exhaust solutions, adapted to the GTI/Hot Hatch cars to enhance the sound of their sports cars.

From now on, the range has been extended to ever more recent vehicles, even just released, as well as certain renowned Supercars !

The EGO-X range stems from this brand by offering valve exhausts for certain vehicles; to respect the control just like the car does originally, or to offer this type of system to a vehicle which has never seen it before!

You will obtain a double identity for your sport car, both discreet and sober & hoarse and melodious...

Whether BULL-X or EGO-X, the HG-Motorsport exhaust solution will meet your needs to increase sportiness for your car!

Note 1: For the 3.35i a part of the OEM exhaust system has to be taken over and disconnected. (it is about the 50cm long piece of the exhaust system in which the oval flexible pipe is located)
The background is as follows: The oval OEM pipe has a connection diameter of 83mm at the point where our adapter is attached. A production from downpipe in 89mm is not possible due to the position of the OEM downpipe on the 35er models and would mean that this piece has to be manufactured in 76mm. This would represent an 8mm smaller cross-section than OEM and thus a bottleneck. Since we always design our exhaust systems for the maximum possible performance increase, this is the only option.
Note 2: On vehicles with OPF, the OPF is located under the vehicle and integrated into the OEM exhaust system. So, the OEM exhaust system must first be cut behind the OPF, then the EGO-X exhaust system will be mounted with the adapter pipe at the separated point by a clamp.
