Wheelhorse#1 1,670 #1 Posted June 1 Was wondering if anybody has found a decent after market muffler? I haven’t found a decent salt n pepper type that’s not too loud. It’s going on a k181 B-80 tractor so space is kinda limited. Not looking for a stack type really. I have an original Nelson on my other B-80 and man it really sounds great. thx for any suggestions 1 Share this post Link to post Share on other sites
ri702bill 8,388 #2 Posted June 1 "Showerheads" and "Pepper Pots" by design ARE loud.They are short and not well baffled. The C81 style Nelson muffler is the opposite. 2 Share this post Link to post Share on other sites

Found one on Fleabay, pretty pricey . 2 Share this post Link to post Share on other sites
ebinmaine 67,771 #4 Posted June 1 The smallest quiet muffler I've found is a replacement for the older Gravely. Piped correctly you could likely get one under the hood. I'm not a believer in that location because of not wanting my carbs that warm. I've installed a couple like this one on the '75 C160 Automatic. 2 Share this post Link to post Share on other sites

wallfish 17,023 #10 Posted June 2 Been using these for years, mostly on 8hp engines but they're made for bigger engines. Nice low tone and seem to last long. Point it down, space isn't an issue. Might need to cut that extra small bracket off https://www.amazon.com/Stens-105-296-Muffler/dp/B001OKBDOW/ref=asc_df_B001OKBDOW?tag=bingshoppinga-20&linkCode=df0&hvadid=80814156492408&hvnetw=o&hvqmt=e&hvbmt=be&hvdev=c&hvlocint=&hvlocphy=&hvtargid=pla-4584413749306968&psc=1 2 1 Share this post Link to post Share on other sites
