The vendors all have offerings that address both the collector and different head ports locations. If you want to cut up Hall big bores that's okay too, make the cuts so they fit neatly in the trash bin.
Wilkinson produced less restrictive GTS headers in mild and stainless and they are well regarded from a HP perspective on dyno results and look oem.

Yes. They're nice. I think he went to the "squished collector" to get them through.
Even so, you need tube lengths in the 34-36" vicinity and tube od's of 2 inches OR MORE to maximize the performance of the engine.
"Under" headers simply can't do that with the Pantera limitations.
You need to go to 180's to approach that, and even there, you are tuning them for a certain rpm.
The people with the "take no prisoner approach" are going to have the biggest frustrations. All exhausts are going to have some kind of an issue somewhere.
None are going to be anywhere near perfect...but then again...define perfect?
