Rather than creating a complete exhaust system, Active Autowerke opted for a compact design built in a smaller package to deliver more value to the BMW end user.
Just like replacing the BMW factory rear exhaust, the Active Autowerke BMW Performance rear exhaust does it in much the same way, if not better by using a much beefier, heavy duty TORCA style exhaust clamp. TORCA clamps are known for their strength and sealing capabilities to make that tight seal.
Other cool features like height adjustable mounting tabs also help to make this exhaust very east to install.
The system is a straight-through design providing substantial improvements to gas flow over the factory exhaust. Gone is the factory flapper to change exhaust tones; this BMW Performance exhaust doesn't need gimmicks to accomplish baritones or suffer from problems like sticking flappers that will happen due to exhaust build up. Instead, the sound come out non intrusive, with a rich mellow tone and delivers a solid 15+hp, with key gains in the mid-range. Listen to the video and judge for yourself.
The Active Autowerke F3x 340i BMW Rear Exhaust System provides increase in BMW horsepower, great sound and appearance making it the choice for the avid BMW enthusiast.
