JAinVA 4,629 #4 Posted October 7, 2018 The reason I ask is that used rusty junk is about a $100.00 a pop on E-bay.There is demand so luck to you and keep it up! 4 Share this post Link to post Share on other sites

Ya I see that , I try to keep the cost at 60 or less , and its looking like this muffler should fall in that price range , but like I said I cant sell them until they get tested and prove that they will hold up over time , I wont sell junk 5 5 Share this post Link to post Share on other sites

I sell them here on red sq , and on ebay , I sell a lot through facebook , I have a couple of small engine shops that carry them , I do a lot of custom welding work for people with tractors and mini bikes , I have a small shop with most all the tools for welding and fabing just about anything someone would need , some day I would like to turn it into my full time job but here in NY with the taxes so high its hard to do 3 1 Share this post Link to post Share on other sites
kick 72 #8 Posted October 7, 2018 I would be more than happy to do some long term testing for you and report. Also pay for the muffler as well. These are for 300-400 series single Kohlers correct. 1 Share this post Link to post Share on other sites

These are for 300-400 series single Kohlers correct. Count me in as a paying beta monkey as well...My particular interest is in a muffler that really does "muffle" and greatly reduces the noise. I am in a typical neighborhood and my interest is less in power and more in grass / snow without being a nuisance...My old stock one simply provides a resonating chamber now. Sounds cool and tough but very annoying when I want to plow early before work! 1 2 Share this post Link to post Share on other sites

fast88pu 3,324 #14 Posted October 9, 2018 The proto type might have hood clearance issues as the photo makes the exit side of the muffler housing look longer. Just an idea Share this post Link to post Share on other sites

JAinVA 4,629 #17 Posted October 9, 2018 jimkemp, I think by the responses here you have a popular item with a lot of interest.When you are satisfied with the prototype please list them in the classified section.If it is as quiet as the original I will be interested in a couple.Luck,JAinVA 1 Share this post Link to post Share on other sites
