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?
