Felix 145 #1 Posted May 13, 2019 I’m fancying fitting an exhaust stack. I Love the look of them. At the minute it’s still got the old pepper shaker muffler on. Has anyone done this recently? I’m thinking of fitting a cherry bomb silencer. (Not sure if these are available in the good ol USofA) what size is the pipe that comes out of the engine block? what do you use as a support bracket to stop the stack either spinning and pointing down or vibrating and snapping off? 1 Share this post Link to post Share on other sites

But there too hard to ship overseas , I wish there was a cheaper way to get them over there , the last quote I got was $105 US just to get it to England 1 Share this post Link to post Share on other sites
Sparky-(Admin) 19,651 #5 Posted May 13, 2019 I’m a fan of stacks. Never had the type that your looking into tho. Both my 8hp Kohlers have 1” threaded exhaust outlets. My stacks are small diameter, light and not to tall so I did not add a support. 1 Share this post Link to post Share on other sites

Pullstart 59,906 #7 Posted May 13, 2019 The block either has a 1” or 3/4” npt pipe thread, most likely. Putt Putt has a Cherry Bomb, and I welded the silencer core of my Honda Shadow 750 into the outlet and added a tractor flap cap. I added some support from the engine block to a two piece clamp and welded the top half of the clamp to the pipe nipple. 1 3 Share this post Link to post Share on other sites

Felix 145 #9 Posted May 14, 2019 Some nice looking exhaust there! I need to try and source some the pipe work and fittings over here. then I’ll make a start fabricating something. Some nice ideas there thanks. 👍🏻👍🏻👍🏻 1 Share this post Link to post Share on other sites
