Muffler clearance issue
2020 Ultra S&S GNX. Belt tensioner cam plate hitting the muffler. Loosened up the bolts and muffler clamp but seems to be no adjustment to clear it. Left side has about 3/16 of a inch or so clearance. Anybody have this issue with S&S?
As I recall, when I bought 4.5" slip-ons, I noticed that Rinehart doesnt recommend theirs for certain baggers. Same issue. So I put Khrome Werks 4.5 cans on mine. Ran into the same issue you have. I loosened up the exhaust system after taking the right slip-on off. I beat a dent in the right can with the round end of a ball peen hammer right where the adjusting cam was hitting it. Put a thick rag, like terry cloth towel overy the muffler so you dont mark it up. Just a slight dent. Invisible once installed.
One thing you'll notice, if you have the sag adjusted on some aftermarket rear shocks, when you drop the bike down off a jack the sag will help your mufflers clear the adjusting cam. Now unless you get air occasionally with your bagger, you wont have any trouble.
Edit: Another thing I did was put a couple of washers between the right slip-on and the bracket so it drops the muffler down just a smidge. Completely un-noticeable. Dont use more than one or two washers for each bolt because youll run out of threads on those two 1/2" inch bolts and can strip out the brackets that are welded onto the slip-ons. I didnt do this thankfully, but I noticed I was running out of threads, and fast, if I put too many washers between the muffler and the bracket.

One thing that I discovered on my last two Glides, 2020 FLHX, and current 2022 FLTRXS, before changing out rear shocks, the Premium HD hand adjustable OE shocks (adjusted to just 3) had no sag when I sat on the bike. Ive run a set of Ohlins, and set of Bitubos and when pre-load is properly set up I think I had about an inch if sag.
Take your left bag off, and you and the missus saddle up, and maybe have someone standing by with a tape measure to see how much, if any, sag you get when you sit on your bike with the OE shocks.
