Down the road I plan on adding my loader to this machine, and thought since I had a little time to burn today, I'd play around a little.

I plan on adding a new elbow, and maybe a rain cap, but definitely will be adding some sort of baffle in the process. Notice the tin can patch with a hose clamp.

Once I have everything where I want it, I'll add a crutch, but figured this is ok for test fitting.

Bet it sounds good like that in true duals!

I had a broken manifold on my 1886 that one of our good sponsors helped with replacing.  I'm sure someone can help you find one.

To eliminate the stacks, you could mount each muffler to the stubs that are screwed into the block. Basically unscrew each 90* that you have on there now and attach the mufflers directly to the stubs. Each muffler would then be directed out the sides and shouldn't have clearance issues with the loader either.

It does sound pretty great, but a bit louder than I like

I quite like the stacks, I would like to add a better style muffle, such as a small Ford tractor muffler, I think it is the 9n or something like than.

Any suggestions?

The cost is what holds me back.

There really isnt anything wrong with the manifold, it's the 1 piece log style. The elbow after the manifold is junk. Since the manifold is good, I'll use that, and just replace the elbow up. I'm going to Fleet Farm this weekend to take a look see. I may go with a different muffler all together?

I'm only running a stack to keep the hot gasses off the hydro lines on the front of the loader. If it weren't for that, I'd probably leave it well enough alone.:)

Austen he definitely has something different coming out of the block to accommodate the pipes and twin stacks you can't come straight up out of the block he won't clear the hood, the pics in this post show the factory exhaust flange , you have to fab up a flange to attach to the exhaust ports on the jugs then go horizontal before getting vertical , also here is a pic of a factory Kohler exhaust manifold. Just an FYI buddy I know your '86 has a different set up :)

IMO you'd have a lot of weight hanging off the bolts into the exhaust ports on the jugs,the relatively small material of the cast iron around the exhaust port that is drilled and tapped for the manifold bolts won't like the additional stress,I'm surprised you're not seeing some metal fatigue with your present set up based upon vibration. Again IMO you'll need some fabbed up bracing.

Just an FYI if it's your loader off your 1455 vertical is your only choice for the muffler on the LF Bolens with the Kohler twins unless you want to re-engineer the set up . I only know of the Johnson 25 having enough clearance to have the muffler remain horizontal.

Yep, vertical was what I am planning on doing. I never went yet to look at mufflers as my work schedule had changed, and now with the snow who knows if it will get done this year. I have seen some really thin mufflers that I think would work vertically, but I rather not go that route anyway. ;)

This is the muffler I used on Alice. Sounds real good on the Kohler M18!

And here's the 'crutch' for it.

This is what I have on mine;

I have an industrial engine in there.
It came with those mufflers. And separate manifolds.
I added some pipes to make them fit.
