Another impression of the M3. We have already seen a lot of tuned versions of the M3 but this is the first one I ever see from Royal Muffler. A tuning company from California I’ve actually never heard of before…

Royal Muffler has been around for 30 years so I personally find it very strange I’ve never heard of them, being a BMW fan.

Many details are yet unknown but we do have some pictures and from those we can tell they installed some wicked rimms, an agressive styled bodykit and a custom paintjob. Royal Muffler claims it is a total rebuild project so we can assume that there will be some major changes under the hood aswell.
