i reused my about a year ago and no problems with it yet.

when i first put on my mac o/r h, i used the stock gasket which worked fine the sveral other times that midpipe was taken off/put back on. but not this time, this time of all times (below freezing out and i was doing this outside) it decided to not work at all. turns out mac had included this new gasket that i hadn't notticed. threw that on there and everything is fine. oh, UNPLUG your batery. the starter is right next to the header to mid pipe flange and the first time around i scarred the **** out of myself by hitting it with the socket.

Got the x-pipe on with no problems. Thank God. I still haven't got my cat-back in yet but I tell you, the stock mufflers sound wicked without cats in front of them. Sound like its got flows on it but doesn't.
