Although I am an E46 M3 and E90 M3 owner, I just want to applaud you for your great engineering and devotion. It is rather rare to see this type of fabrication and design amidst us enthusiasts here on the many BMW forums.

I personally am thinking about building a custom SPipe, XPipe, and Muffler for my own E46 M3. I haven't been too happy with the systems that are currently readily available. So I'm hoping to design something that complements my SS V2 Stepped Headers.

I see you're located in IL, it would be great to get together one day and hear your beast and maybe discuss some theories of exhaust fabrication.

I really wish I had a Z4 right now......
