When I ordered my pipe and bypass from BVM, it came with a separate bellmouth, so it could be set-up without the bypass if you choose. If it is set-up to run the bypass, and you choose to leave the bypass out and run the bellmouth, you will have to build engine mounting rails, b/c the bypass serves this purpose and there is no provision for mounting the engine otherwise.

I'm not sure who is making BV's Mig pipe now, but it does look like it could be a Tam's product, but I do not know for sure. The quality is so good; if it is not a Tam's pipe, I'd be surprised. Tam and BV have worked together in the past, so it is possible it is. If you call Tam and ask him for a pipe for the Mig and he says, "you orda for BVN", then you'll know for sure. U da man TAM!
