Active Autowerke is proud to announce the release of our Signature F8X M3/M4 Exhaust System.
This system is the result of countless hours of R&D to obtain the perfect combination of performance and sound. Constructed of 100% 304 TIG welded stainless steel, we have created a modular exhaust system that will provide enough flow to support power levels way above the stock S55.
The stock S55 midpipe is a dual pipe system from each turbo that leads to the rear muffler. The resulting sound is far from pleasant, and without any real scavenging effect the turbo lag is fairly pronounced. By converting to a single 3.5" pipe directly after the downpipes, our system promotes exhaust scavenging along with higher exhaust velocity to produce a quicker spool, more power, and a much smoother exhaust note.
We believe that we’ve built the best performing exhaust on the market. With the reduced back pressure and large single-pipe design you can expect exhaust velocity to remain as high as possible throughout the entire system. Our design is also capable of handling much higher power levels than stock. It’s over engineered to have no issues handling the increased exhaust volume from extensive modifications including turbo upgrades. All Active Autowerke exhausts are designed and manufactured for performance, and our S55 exhaust is no different. Instead of copying the OEM exhaust, we started with a blank canvas in order to create a system as close to perfect as possible.

Easy to Set up
Style: 1 to 1 IR Repeater
Works great. Have Sonos playbar mounted behind TV and it does not support eARC, only IR, for use with AppleTV remote. This solved problem.

Works just as advertised!
Style: 1 to 1 IR Repeater
Super east to set up. Haven't had any issues in our very long living room so it must work at around 25ft

Works as advertised with minor aiming quirk
Style: 1 to 1 IR Repeater
Setup was quick and straightforward. I plugged it in, placed the receiver, and it started relaying signals right away. It does exactly what it is supposed to do and successfully extends remote control range to my equipment without any complicated configuration.
The only issue I have noticed is that it can be a little directional. I sometimes have to angle my remote slightly from the left or right instead of pointing straight at the receiver for it to register consistently. It is not a dealbreaker, just something to keep in mind when deciding where to place it.
Overall, it performs its intended function well and is a solid option if you need an IR repeater, especially considering the price and simple setup.

It works!
Style: 1 to 1 IR Repeater
I’ve been wanting to use my DVD player more often, when I work at my desk, but it’s situated too far for the remote. This device works perfectly, now I can enjoy so many old DVDs without having to move or rearrange my whole setup.
