Will these fit my 88 5.0L owner said he had them made for a 302 in a ranger http://calgary.kijiji.ca/c-ViewAdLargeImage?AdId=147560842&back=-1&ImageIndex=0
Looks like you'll need a custom fabricated H-pipe/x-pipe to go along with those....
do you think it is worth buying for $40? I was looking for a h-x pipe second hand too.
You won't find an H-pipe to fit those-you would have to get one made. I would stay away from them and get something you know that fits. Check out some of the mustang forums-people are usually selling used headers and h-pipes cheap.
For just a little more,you can get a good used set from Ebay.If you buy factory Mustang headers,you can get those dirt cheap (I've sen them sell for $15-$20).By the time you buy those....IF they fit right,then have an H-Pipe (or X) fabbed,then you'll still be spending too much.Grab a set for a Fox Mustang and call it good (Guys over on the Corral forum sell them at almost give-a-way prices),plus,a Mustang H or X-pipe will bolt right up to the headers like it belongs there.
