Greentored 3220 #52 Posted August 31, 2020 Ok, started with a cheap 1 3/4 fiberglass wrapped baffle for Harley drag pipes. It passed the 'yell test' (you all know dang well what the yell test is, dont deny it) I had to cut it in half to fit down inside the Tractor Supply muffler- it worked beautiful- super quiet! ...til I put it under load. Now it sounds like a combination of a popcorn popper and a rapid fire spitball being shot through a straw, and not much quieter. On to plan B- any of you guys running a Gravely muffler? Wondering about using that, coupled with a baffled stack? Share this post Link to post Share on other sites

Your other option is to buy a late 70s Cub muffler off of a 10 horse Kohler. 12 horse Kohler. Cut the mounting tab off the side of the muffler if you want to. Turn it up as its own stack. Those are extremely quiet. That's what I have on my Patriot Horse which is a Kohler 8. Deeper tone. Much less noise. Just looked up the video of your Charger running- that is perfect! I can turn it up and attach a stack to it, and if its too noisy, I can drop a baffle or second muffler onto it. Thanks!! 1 Share this post Link to post Share on other sites
Greentored 3220 #55 Posted September 14, 2020 The gravely muffler arrived last week. I love it- really tones things down. However, my age is showing. When turned upward and a section of pipe added, it was still too noisy for 2 hours at a time cutting grass. Angling the muffler down and ahead is not as cool as a stack, but cutting the grass was MUCH more pleasing. Think im gonna chalk it up to 'old man' and skip the stack on lawn duty- all the others have one, so that's acceptable, right? As a bonus, now I get to play with some ideas for a wild (but quiet) side pipe or something 3 Share this post Link to post Share on other sites

Greentored 3220 #58 Posted October 14, 2020 (edited) A quick update, and changing my mind again- imagine that! Picked up a 312-8 a couple weeks ago for a deal I couldnt pass- all maintenance just done and ready to roll. I backed it off the trailer and cut the grass, and quickly realized how those things just purr with that factory muffler, and how I could just 'stack' the outlet and have a very quiet, stacked machine, much like my ol 520H was. SO, with that being said- where do I find these factory mufflers? Research shows they are not made anymore? I cant find a Nelson replacement either. @jimkemp tried to message ya, but it wouldnt let me send. Can you do it?
