Stack Pictures

Mine has the same side exiting exhaust at the top you have.. I wonder if that is why it is so dang loud, being able to focus the exhaust at a certain point instead of straight up into the sky.

Mine was too loud for me, I hang a quiet line muffler off it when I am using it at home to keep the neighbors happy. It is only held in by a bungee so once in a while they get to hear the sound of raw power..lol. :biggrin2.gif:

Ive got $35 in the stack on my 149, $30 for the muffler and $5 for the bend at at local place, its very quiet because of it comes off the stock muffler.

Here's the stack on my 100.

Those look really cool but I hope you guys are bracing them properly...that's a lot of mass flopping around out there. I'd hate to see somebody get a cracked block from having the exhaust port carrying all that weight.

[mstetar]

all the weight from mine is supported by the stock exhuast mount on that heat shield

I'm not sure that's enough...take a look at drysumpjet's initial post in this thread. What he did was overkill for a straight pipe, but looks to be very strong. An excellent solution, in my opinion. That OEM muffler shield is pretty flimsy and isn't designed to have all that other stuff hanging off it. The exhaust port is carrying some of the load, too.

Those F-cub mufflers aren't particularly light.

Overkill yes.....but sooooo cool looking!!!

I have put lots hard hours on this tractor, mainly rear blade and box scraper work, requiring lots of rough ground travel. Nothing cracked, nothing loose, all good. I'm not regretting the overkill bracketry a bit, it's very solid, the key was to secure the pipe to the bracketry with a muffler clamp.

I did update the insert muffler, I had Ken at Car Chemistry www.carchemistry.com make me up a custom legnth insert. Orginally, it was a 6" insert, now it's got a 12". Ken will make any legnth insert you want.
It actually idles and wide-open/no load reasonably quiet, but when loaded, it still barks!

Thanks again for the Kudos!

ACecil- tuff looking tractor! beauty is in the eye of the beholder! i lean with Matt G. on the fears of stacks. but hey, they do look cool! and i do favor a more quiet 71. i'd like more of a drag-style exhaust pipe.
