There are a lot of modded M3s and M5s coming out of our shop for sure. A few of very many more can be seen on our customer blog here:

A G-Power twin s/c E60 M5 is currently being built by us right now, then we have a G-Power supercharger going on an E92 M3 very soon, along with an E90 M3 lined up for the AA supercharger when it comes out.
Definitely drop by the shop if you want to see some beasts being built!
If someone local is looking for an AA exhaust for their E9X M3, we can cut an absolute STEAL of a deal on one that's in stock brand new!
