European Exhaust
If your seriously looking for a new high flow header. that doesn't cost $5000 or more, my sugestion is to take your factory header off the engine to a reputable custom exhaust shop, and also take measurement of the clearances of the engine compartemnt where the header sits, and tell the exhaust shop to make a "highflow" model with or header as a donner part.
At most you'll be looking at 1500-2000 dollars at the high end.
