krazy_horse 59 #1 Posted September 3, 2012 Cutting grass friday I noticed my very quite B-80 was sounding louder than normal. The pipe is splitting at the bend.I am looking in the NAPA Out door power catalog and see a replacement for a Gravely #7-03679. Will this work on the 8 horse and will it be quiter than the can mufflers from the big box store.? Thanks for your in put. Share this post Link to post Share on other sites
ol550 830 #2 Posted September 3, 2012 Have the Gravely muffler on a GT-14 and a 8 hp Kohler on my regular mower. Quieter than the pepper pot style. Mounted mine verticle with a turn down to direct the exhaust fumes away. With a little fabbing I am sure it could be mounted in front also. Share this post Link to post Share on other sites
Kelly 1,033 #3 Posted September 3, 2012 I think I have a goodB-80 muffler if you want stock, send me a PM and I can check stock. Share this post Link to post Share on other sites
squonk 43,899 #4 Posted September 3, 2012 That Gravely muffler isn't any louder than the stock Nelson muffler IMHO. My neighbor has a 14 HP gravely with it and it's the same as my C-160 as far as noise. I've got an old gravely muffler I'm using to mockup a stack for my Kohler powered Power King. I am going to buy a new one when every thing is fabbed up. Not cheap. Near $50.00 :hide: Share this post Link to post Share on other sites
