Hey guys,

I'm going to be working on installing a cat back this weekend and I want to have a few things prepared.

My parents live in a small town and getting parts on the weekend can be killer.

I'm wondering if anyone had a repair manual for a 2003 Mustang GT and could tell me the bolt sizes or if they are special bolts I would need to hook the cat back to the h-pipe.

I know it says to use the ones on there but I don't trust that I'll be able to get them off with out just cutting them.

Any help would be appreciated.

Thanks guys.

The bolt size is a 14mm. Just soak them with some PB blaster and they should come off easily and will work fine with the new catback.

mine came with new bolts and clamps, what brand are you getting?
+3 for pb blaster or something like it.
you can hit them with a hammer and swear at them while they are soaking.
