Talk me into Fenderwell Headers

I've never run full fenderwell headers, just the semi chassis headers where only a few pipes dump into the fenderwells. My 71 Duster was previously cut for fenderwell headers. I don't believe, with the holes that you have to cut for fenderwells, that you are hurting the structural integrity of the car. You can always do as I'm doing and only cut what is necessary instead of the large hole they have you cut with the templates.

The exhaust and subframe connectors interference is not an issue. The exhaust pipes will run in between the drive shaft and the connectors on each side. I'd include some photos of the exhaust on my Duster, but that computer crashed and the car is long sold.

The only thing I don't care for on full fenderwell headers is your tire limitation. You are limited to a smaller tire so it will not hit the pipes. I've seen what fenderwells can do to a tire just during cam break in. Even though we kept a water hose running on my best friend's tires, it still ballooned both of them. We never made that mistake again.
