I didn’t know what exhaust set up to go with. After a year and a half of searching for the perfect exhaust, this is by far the best sounding exhaust I’ve ever heard with the S55.

Addison Lopez
Best Sounding System For The F8X Chassis

I purchased this exhaust system in hopes to give a deeper tone to my F82 M4 and I was blown away by the build quality alone! Packaging was great, very fast shipping. The exhaust comes with a propriatary valve controller as well as all the wiring needed. In my case, I used the OEM valve motor that came off the stock exhaust and it mounted to the Valved Exhaust's muffler flawlessly. The muffler size difference is incredible. Less than half the size of the OEM muffler and with the valves closed, its actually quieter than the stock exhaust, but with a press of a button, it awakens a monster. Perfect tone, no rasp, no drone. Hands down the best sounding exhaust system for this chassis. Install was quick and painless (I did it in my garage on jack stands in around 2 hours). I am more than impressed.
