MN 88 convertable headers

The most common headers for an 88 13B na seems to be the 70-1152 pacesetter set, but they say "will not fit convertable" why is that? Is there another reasonable priced set out there that will? I built a custom set for a v-8 years ago, a 2cyl should be a breeze. Do the same 32"to34" primarys apply here? what size for a street engine, 1 5/8" primary into a 2 1/4"?

Pacesetters are pretty much cheap junk. If they say it will not work on a convertible, it's because it will hit the additional chassis brace at the rear of the front subframe. Coupes do not have this brace. If you want a good header, go with Racing Beat's. It's 2" going to 2.5"

And "2 cyl"?! That's insulting. No cylinders. All rotors.

Rotary's have much stronger exhaust pulses and a properly designed header makes a lot of difference.
