adgecutler 83 #1 Posted February 21, 2016 I have had a quote to make up an original pattern Kohler exhaust but in stainless, but, the price dropped considerably (as you'd expect) when having a batch made up. I sadly don't have a wealth of cash to spend but wondered if anybody else has had a batch made and if any might be available? I'd also be interested in any new old stock that may be around for 10 & 12 BHP (the same size if I remember correctly). 1 Triumph66 reacted to this Share this post Link to post Share on other sites
ranger 373 #2 Posted February 22, 2016 I made this one a few years ago for my 312-8, I took apart the original, not difficult, it was rusted out, I copied the internal volume, pipe sizes, number of holes in the internal pipes (baffles) The only difference was, I fitted a 'stack' outlet, it is sooooo quiet. Stainless from the internet was used, I made 'hammerforms' to shape the ends and centre baffle, all 'tig' welded, and then I cut the outlet for the stack the wrong shape and made the mistake of filling the gaps with weld instead of fitting a 'patch' / 'doubler'. I can't remember what it cost, but the materials were not that expensive. . 4 meadowfield, Stormin, sten and 1 other reacted to this Share this post Link to post Share on other sites
ranger 373 #3 Posted February 24, 2016 A bit more info, the reason I copied all volumes, dimensions etc, is, the original carb is a non adjustable main jet Walbro, then I bought a Kohler adjustable carb from the States and rebuilt that,but never got around to fitting it, Share this post Link to post Share on other sites
