Refinement Meets Performance:
The OEM F8X exhaust utilizes the services of middle and rear silencer as well a pair of exhaust valves. It is supposed to be a freely-flowing exhaust that produces an external sound that meets the demands of a M3 or M4.
The middle silencer has a small crossover that allows for noise dampening while the rear silencer (muffler) has a reflection chamber on either end that re-directs exhaust gases to the opposite side they entered from (drive’s side exhaust exits on passenger side). When the exhaust valves are closed, this helps eliminate the back pressure buildup that occurs during noise dampening.
After analyzing the factory exhaust, we realized less would be more in regards to our F8X exhaust.
We began with a complete redesign of the mid-pipes. This involved drastically increasing exhaust flow as well as reducing the uneven, out-of-sync turbocharger’s sound that many F8X owners have complained about on the forums. We were able to achieve this on our F8X Mid-Pipe (sold separately) by using a single pipe that not only cancels out the offensive sound, but allows unrestricted exhaust flow.
The most noticeable difference between the Active Autowerke F8X Rear Exhaust Section and the BMW factory exhaust is how we utilized the muffler. Our design incorporates two mufflers that create a huge resonance chamber to further cancel out the weed eater noise.
This design also allows exhaust gases to crossover freely without being forced in a certain direction – eliminating back pressure without sacrificing that deep, aggressive rumble that some turbocharged cars are known for.

PREPREG is a common term for a reinforcing fabric such carbon which has been pre-impregnated with a resin system. This resin system (typically epoxy) already includes the proper curing agent. As a result, the prepreg is ready to be laid into the mold without the addition of any more resin. In order for the laminate to cure, an autoclave production process is used, a combination of high pressure and heat.
- Maximum strength and performance characterictics. In a hand layup production process, it is difficult to achieve 50% fabric and 50% resin content. Typical hand laminates, even when vacuum bagged, end up with a significant amount of excess resin. Excess resin increases brittleness and reduces overall strength properties. On the other hand, most prepregs contain around 35% resin. This is ideal for maximum cured properties and generally impossible to achieve in normal hand lamination.
- Uniformity and repeatability. The prepreg is of uniform thickness and each part coming out of the mold may theoretically be the same. Vacuum bagging technology may have some errors in processing, but prepreg ensures production consistency.
- Reduce curing time. After the thermal curing cycle, no need to wait for the standard 48 hours can be fully cured.
- Aesthetics. Although prepreg processing still requires mold preparation and demoulding, prepreg processing eliminates air bubbles, makes it easier to obtain a smooth, glossy surface as well as eliminates any seaming lines.
