Well….had been working for the past few days trying to get the bolts out of the exhaust so I can put the new one on…just couldn’t get them loose no matter what I tried…so I had a brainstorm to take it down to the shop that used to do all the work on the MX-6 and see if they could do it….5 minutes and an impact wrench was all it took to get them both loose and now I can change it out any time I want….it is a little loud since I didn’t want them to re-tighten them so I couldn’t get them off…and, it didn’t cost me anything but I did give them 10 bucks to buy the guys donuts tomorrow…so it looks like tomorrow aft or Thurs I will be changing out the old one for the new and maybe we can shoot pool this week after all….
