Hi, just curious if anyone has used or has spec'd any results on the BD exhaust manifold. After seeing their web site displaying the differences between stock and their product, I used an old infra red camera setup and sure enough, a huge hot spot at the restriction. Why on earth would they do that? to ease assembly at the plant?

Besides increasing the life of the motor, the balancing effect of the exhaust has to increase efficeincy and power. I have not even got to the tuner stage of my buildup, but this seems like a plus in more ways than one. Anyone?:gearjamin

Same here just heard rumors. I was looking into it for when I install gauges. I'll probably be removing that manifold to hook up the pyro and the BD is suppose to have a hole taped already for the gauge. Kill 2 birds with one stone.

I also hear it improves smoke a little :rolleyes:
