You can find some great deals on headers..... Like anything you get what you pay for. I had a set of Kooks that I just sold for $650. They were very nice. The only reason I am not using them is have some Cast 427 cogs I used......

I have learned from my Mustang that not all headers are created equal. I have had some garbage and some nice ones. If you have the cash, throw it into the exhaust, you wont be disapointed!
I dont know if BBK makes anything for our Galaxies but they are affordable and the quality isnt bad. I have ran Flowmaster, Mac, Hooker, SLP, and Magnaflow exhaust. Out of all of them, I like the Magnaflow the best. My 64 breaths through 2.5" Magnapacks. My 60 breaths through 2.25" Flowmasters.

As far as the X member, you can whip somehting up with a torch and welder. Im not sure of the measurements.
