Cougar is pretty well up to speed with the diamond eye exhaust. We both have had our issues. Its a good system, but the 4x4's have a driveshaft clearence issue. They have updated the down pipe, but its still pretty close. For the money, it can't be beat. I got mine for under 300 delivered.:yeah: I had over 600 in my Stans headers system on my 89.:ouch:

what is the best exaust manifold to go with the diamond eye 4" system?

I am also in the market for a reasonably priced 4 inch down pipe. I need just the down pipe as I already have the full stacks but I am upgrading to an HX35.

My turbo is an HE4-whatever-ve on an ATS T4 footed manifold with an inch of spacers on it, so it sticks pretty far out over the frame rail. After I got a custom flange welded onto the end of the Diamond Eye, the downpipe fit perfect. I was surprised it was bent so well, no clearance issues at all. I could go at least an inch in any direction without hitting anything, somehow I have more clearance now than I did stock.
