Bad-mouthing a company for ONE mistake is quite unfair in my opinion. If this was something that happened multiple times then yes, you're entitled to warn everyone of a company's bad policy but just once? Please.
I cant see how one mistake(that was rectified, mind you) is fair grounds to accuse a company of bad business. But hey, I actually see this as a sign that the demand for the Stealth exhaust is high enough that it goes out of stock fairly quickly so its a quality product. I cant wait to order mine further down the road!
