well up here it cost me a couple hundred less. I understand that Heath is a great guy with great service, but on the old site there was a guy last year with Heath injectors that leaked... now they replaced them and everything, but he was still out the installation time etc... so I wouldn't say you didn't have to worry about quality at all. I think that Heath the the best guy in the business of 6.5s, but it's ok to acknowledge that he is MUCH MUCH MUCH more expensive for the SAME stuff. 4 inch exhaust? way overpriced, x-over? same deal. His glow plugs can be purchased from pep boys for much cheaper than what he sells them for, and I know he has a warrantee and everything, but with the saved money you could just go buy extras, and you'd be in the same boat. Like I said I love Heath, but cost is the major issue with them, and its perfectly ok to admit it here. He has the BEST price on ECMs, which is really nice, since from what I've read he also has the best.
