its stamped, starts with a 1.75 outlet, cut to length for whatever exhaust flange size you want.

All the miata fags say to run 2.5, I'm thinking 2.25. The primaries are only 1.375 16g. What do you think?

I could probably draw a template. How much of a difference is there in the way a merge collector functions vs a stampe? looks like mock up would be easier with a merge.
