Lincoln Mark VII Exhaust Options?

[79Clunker]

I have a '91 Mark VII LSC SE and have been wanting to do the exhaust up on it. I'm looking at starting at the headers and doing it all and since it has the 5.0ho I would think that most mustang exhaust would work. It has been hard for me to find information on this so if anyone knows a good system for me let me know.
I want headers, o/r H-pipe, a mufflers I don't know if I want long tubes or what kind of mufflers I want. I just want to make sure the headers and h-pipe will fit and I want to get as much HP as I can from this upgrade. All opinions are appreciated.

on my 91 mark VII lsc i went with bbk-1515 for the headers bbk-1507 for the h-pipe for the rest iam currently having flowmaster custom build one of there mustang LX kits. the h-pipe and the headers fit like a glove.
