Problem found. You need a cutting tool with more nuts. Hell, Harbor Freight will have a $20 air die grinder that'll work well enough to do the job. The Dremel is for final finishing, not hogging out that kind of metal. You're also using plenty of cutting oil, right?

Yea, you need an air powered 1/4" die grinder with a couple of large football shaped burr bits for roughing. Then a couple of smaller diameter burr bits for finishing. Ball shaped. If you want to go deep into the manifold. Then you need burr bits with a 6" shaft on them. You'll burn up the Dremel on the first port you try to do. I get my die grinders from Sears. I burn them up, and they give me a new one.

Local Sears store has them on stock to boot.

Just wanted to thank rusty for the heads up on the die grinder, so far its working great. After further measuring the gtm exhaust manifolds the hole is 1/4 smaller then the flange where it connects to the turbo slowing the air flow down. Will take some pics tomorrow and show my progress. I will wait and send these to vsr because if they can fabricate these I want you guys to have the openings the same size to allow more exhaust flow going to the turbos. Stay tuned!!
