Interesting. It's well known by now that I dis-like the lawnmower sound of the stock exhaust on my 2011....but hafta wait a bit for a new muffler.
I went ahead a bit ago and hole-sawed the end of the muffler and pulled out the 5" piece that's part of it. (some have spoken of it as being stainless, but mine definitely is not) Didn't have any problems with the hole saw, just kept the speed down, the pressure light and hit it intermittently - only cut 5 seconds or so, give a quick break and then some more - I've done a lot of this over the years. Hole saw is still sharp.
Several people have mentioned that after pulling that component they reached in with long nosed vice grips and pulled some other baffle. All I can see is way down there a part with what looks like angled vanes on it. You'd need some kind of extreme vice grips to reach that, so I fired it up for a listen......and was immediately glad I hadn't gone any farther.
Yes, the tone is deeper and sounds just right, but when accelerating it has a sharp bark that I don't like. Haven't had it for a real run yet, just a mile or so down the road and back and seems like it's a little stronger. We'll see.
Question - now that I have a common reference point, maybe someone can recommend a muffler for when the time comes. I like the deeper tone of this mod when just running along but don't like that sharp bark at all. Many of you have done or have seen this mod, so which aftermarket muffler would come close to doing what I'm asking here ??
Also, the last few days I've noticed a mild, intermittent backfiring when de-celerating. Is that a sign of tight valves ??
