As this is a brand new system, and is currently in production at Remus in Europe, there is not any video clips or dyno charts right now.
In regards to that, this is the information I was provided:

SOUND
Free flowing the RS’s (Rear Silencers) usually creates good gains in sound and performance. But you can’t just arbitrarily free flow RS’s. Everything, from diameters of the perforated resonator tubes and tips,
the splitter style, the opening size in the screens, the density and thickness of the stainless steel steel wool between the screens, the size, shape and frequency of the holes, etc., etc., all have to be engineered for the type of engine and H.P. rating.
Many of REMUS’ competitors have copied an original RS or two, but the design is different and continually evolving in so many applications in our sport exhaust systems that they cannot possibly keep up.
So if a competitor’s system happens to have a good sound, for the most part it was a “happy accident” not a smart, engineered design.
POWER
Power wise, we don’t have a credible dyno comparison on the newer 1M’s as of yet. But extrapolating from the dyno information and anecdotal information we do have, we are confident these new
“Titanium2’s” and “Sports Labels” will net somewhere between 3 – 8% gains in H.P. and torque. Perhaps we will see this, around the time these systems become available as REMUS has an audio
correct dyno test cell at their factory that is the envy of every exhaust manufacturer. Depending upon how long they can keep their R & D car is what determines whether we get a dyno comparison from
them or not.
From all over the performance spectrum, here are a few results from the REMUS dyno: A BMW E92 M3 sees a 2% boost in top end (10 H.P.); a VW GTI V 2.0L Turbo sees a whopping 7 – 10% across a broad
range of mid range R.P.M. (7 H.P. at the 3500 range, 18 H.P. at the 5500 range); a Porsche Carrera S sees a 7% gain (20 H.P. increase in the 5500 R.P.M. range); a BMW Z4M sees a 3% boost in peak
R.P.M. (9 H.P.) an Audi A5 Turbo Diesel sees a 2.5% boost in lower mid range (9 H.P). All of the above dyno results have been published in over 50,000 REMUS print catalogs worldwide, as well as
REMUS’ web site.
Based on that knowledge, we’d say the the 1M will see similar % gain results as the VW Turbo above. Turbo’s benefit from free flow exhaust more-so than do N.A. cars. Since it is likely REMUS builds
the O.E.M. system (we think – but we will likely never know for certain) it may not be quite as dramatic. But, if mounting the RT’s (Racing Tubes), the results could end up even better. If anyone has credible
before and after dyno results on a REMUS mounted on the 335i, those results will be comparable.

With that said, I was told the system should make a realistic gain of about 8HP based on what we've seen with the N54 335.
