Well, you highlight part of the issue. That being it is the entire exhaust system that needs improvement, not just the headers.quote:Originally posted by r mccall:quote:Originally posted by PanteraDoug:
I can't think of any under car headers that work to maximize the power potential of a Pantera.
The all have some sort of issue.
Pat Mical sells a set of headers that make great power, fit perfectly and have a 3" collector .
I built a 3" under car exhaust system for my car (using his headers and Borla XR-1 mufflers)10 years ago for a 670hp C3 Yates
engine and they were excellent in every way ( except for the price. LOL )

Many just want to integrate the headers to the existing factory tailpipes and mufflers. They just want a bolt on OR can only do a bolt on.
Plus, I'm pretty sure that Pat's headers are not off the shelf items. He makes them for you on your order.
Part of the issue also is the noise generated by the system and it seems like any muffler in a Pantera is about twice the loudness of that applied to a front engine car that has enough length in the system to tame some of the beast roar.
I have noticed that it is far more common to dyno an engine with "dyno headers" rather then the exhaust that is going into the car? Right there that is almost like a "hocus-pocus" deal where one really won't know what the actual gain was without testing with the intended exhaust system.
