That's funny because I just bought his intake setup off his car and i'm getting the same TFS 215 heads. I'm hoping for 460+ hp through an m6.

The gains from that flowmaster merge is amazing. I'm going to ask him for further details on it.

Saved me 500-600 bucks compared to the CNC 215's and they flow just as good as the CNC version. Might want to take that into consideration. Just trying to save you a buck.

you DONT hve to get the flowmaster although the merge is nice on that piece. The magnaflow y pipe comes in 3'' in and out and also stainless for a good price. That would a better option as well. Its not about looks here, we are just trying to help you rid of nasty sounding exhaust gases and also get you more usable horsepower
