sounds like what the average is. if i remember right that is what chad at alligator and newly at underground diesel performance are selling them for. They are both great to deal with.
I believe you mean 409 or 304. Just don't see why you would want to take off a factory stainless system and install an aluminized one. But if you aren't around salt and need to pinch every penny I guess it's worth the savings.
Your right on that one there aint sh!t in Odessa. If Alum is the only kit in your price range then go for it but if you got the cash to spare then I would go SS alot better quality and it will last longer than the truck will.
