FatJackDurham 318 #1 Posted July 25, 2018 Hi, What kind of exhaust options are there for a GT-14 with the standard K321 engine? I don't think I'd like a vertical stack, though, I'd kind of like a horizontal muffler like the Onans on the 416. It'd be cool if it actually muffled the engine, too. Right now the can-thing that's hanging off the pipe doesn't really seem to make it any quieter, beyond eliminating the higher frequency pops. 1 Share this post Link to post Share on other sites

What you have on there is likely more of a spark arrestor than muffler. I have a stack on both of mine and my honey has a pepper pot that doesn't quiet much. On my B80 I have a muffler that was a stock item from some horses and Cubs. I just turned it up right. That keeps the noise down pretty well. 1 Share this post Link to post Share on other sites
Aldon 4,826 #3 Posted July 26, 2018 For my GT16 Restomod I used the muffler off 400 series tractor with only slight mod to the mounting bracket. The 341 and 321 are basically same. So same set up would work on the stock GT14. 3 Share this post Link to post Share on other sites

19richie66 16,942 #5 Posted July 26, 2018 Hate to answer for Aldon but I think that is what he used. I made my muffler(although not super quiet) modeled after the 418-a. Same length and diameter. Just no packing in it. 2 1 Share this post Link to post Share on other sites
