During the L O N G winter months here in upstate NY, I found a SE Nightstick Muffler for my 2010 FLHX at a great price, less than a hundred bucks on Ebay. I bought it and when it arrived I looked it over, no scratches or dents it wasn't new but I was satisfied. I put it back in the box and stuck it away and began waiting for spring. After the snow finally left and I was able to get the bike out I began the transition from the stock exhaust to the new Nightstick. All went well until I tried to tighten the bolts on the rear. They had been overtightened and had stripped out the threads in the muffler. They wouldn't tighten up at all. I was able to drill out the bracket and Muffler holes then re-tap the muffler to accept 3/8ths bolts and lock washers. After some elbow grease and grunting all is well. The bike runs and sounds great. My lesson and maybe a lesson for anyone is to check everything you get from ebay and make sure it is ok before you send that feedback.
