Ok, I'm not going to be a smartazz about this, but who ever said that should be hit with a shovel. Not only does that not make sense, it's just plain silly. MAC makes great exhaust product, as does many other companies. Tell that guy to go jump off a bridge or something.

I guess years ago Mac had a problem with slag from the welds getting in to the egr system and scoring the cylinders but the problem has been corrected I guess I should have called Mac first thanks anyways

First I have never heard of that. I agree that it is possible for the slag to get in there and mess things up, but that is not limited to just MAC. I wouldn't worry about it.

HA HA. You'll have that. Don't forget to lift the motor.

Enjoy. Post some pics when you get it done.

You are correct about prior problems with the quality of MAC headers. They used to have alot of problems with welds at the flanges. I would probably say that MAC has corrected that problem...don't worry about it.
