I was wondering if anyone out there has tried an exhaust system from Stan's Headers out of Washington state? They come in 4 and 5 inch aluminized systems, and use a Donaldson straight through perforated core muffler that has an expansion chamber of some sort. The tech told me that a customer told him it reduced his EGT's by 200 degrees or more ( well, I don't know about that?). Tech also mentioned it got rid of the droan some customers complained of with other systems.
Any thoughts?
Joe.
