So Joey can you give us a confirmation that we can get coated MSDS headers from you? If that's affirmative then I will hold off buying from Marty at this moment (well, he will still get my business by selling through you).
If you can get the bare headers at same (or even lower) current price of $180, adding cheaper ceramic coating, and ship with the rest of the kit for not much more in shipping, I am sure you will have all people who plan to buy bare MSDS headers to use with the turbo kit lining up at your door. I also believe this way all guys originally plan to just use factory precats will try to squeeze another $210 or so to get the MSDS headers. This will be a win/win/win situation. You get higher revenue (and less headache by almost eliminating the need to maintain 3 different versions -- stock precats, WR and MSDS), Marty gets to sell more headers to those originally planning just use stock, and we get incentives to save a buck or two.
Maybe you should seriously consider this?
