any one have/had these? how many miles get outta them? lots road noise? hows the price? thanks in advance

 

My cousin ran a set on his '06 Powerstroke. Not too noisy, dug pretty well, price wasn't bad, but I don't remember him getting much mileage out of them. However, he had stacked chips, aftermarket turbo and intercooler, a manual trans, and drove like a wild man...
