I ordered Mac LT headers over a month ago and there is still no estimated ship date for them. I ordered from Mustangs Unlimited. When the heck is Mac going to ship their headers? Every place I look they seem to be out of stock.
Cancel that order and order some BBK L/T's. They are more expensive but they will last longer, ship faster (assuming they're in stock) and they won't pull oil from your engine and burn it up.
I would but it seems that mac are the only ones that will fit an automatic.

I can say the last set of bbk headers I bought (fox 351 swap) needed A LOT of clean up to fix the welds (slopy) and make the presentable. They also had bad jig clamp crimps in the metal. Look like chit. Doesn't matter too much on a mod b/c they are hidden but were very very visable on a fox and looked bad.

I have never had a problem with my Mac LT's causing oil loss??? 32V's do burn a little oil, but mine hasn't increased after the LT install....
Where did you buy your macs from?
call MAC directly, my friend ordered his mid pipe & cat back from them and got it in about a week............
