Look at the headers from Pantera Pro-formance. They reduced the collector to 3" for clearance to get it through the suspension BUT it's a real collector and ANYTHING helps. The primaries on their GTS headers are also 2".


I dig up this subject.

You say the collector of Proformance headers is 3" but on their site they write 2 1/2" ??????

Beyond this question, do you think these headers are the best for a street engine of about 450 HP?


I would go with what the website says, but I would think that the exhaust pipe is 2-1/2" and the collector 3"?

I wouldn't know which headers are the best. I've got Hall's 180's.

Pat Michal has dyno numbers on his. As I recall, they were impressive numbers.

From what I can tell, they are very high quality and very well engineered.
