Bolens G154 exhaust

iternawheel · Jan 3, 2011

I have a Bolens Iseki G154 with a two cylinder engine. it currently has a horizontal exhaust and i would like to put a vertical pipe. does this engine need a muffler to supply adequate back pressure or could i go with a straight pipe. any input is appreciated. thanks.

Can you just rotate the muffler and add a stack?

My Iseki G-174 with mount either way......I used a chrome hollow table leg for mine and added a flapper works great Ampa <>

mine is not able to be rotated. it has one pipe coming out from each cylinder into the the muffler in two different places. will a straight pipe be harmful for the valves or would it be ok. im just looking for the cheapest way to put a vertical exhaust. thanks iternawheel

My ISEKI is a 3 cyl. Mitisbushi diesel engine and the square flange on the main muffler can be mounted on the side or upright.....yours bein a 2 cyl. maybe has not this option....

maybe you could have something adapted or custom made to work....as for will a straight pipe be harmful on the valves...I don't know what to tell you....

perhaps someone else can chime in here with much more knowledge than myself ....bein' this ISEKI G-174 is my first liquid cooled diesel engine type tractor...my two other tracors were only lawn tractor 1 cyl. air cooled gasoline Briggs & Stratton engines...completely different...nothing is impossible though.... so with that said just be patient someone will be able to help you with the info your lookin' for I'm sure...take care Ampa :thumbsup:

Iterna, I have a TX1500F with the same exhaust.
I don't think you can turn the muffler itself but you should be able to put some type of L pipe extension off of the end of the muffler.

While I have not done this yet it's the only solution I can come up with to keep the exhaust from hitting the backside of my FEL and comming back into my face.
Post a picture of whatever you come up with.

Sideways, I also have a Model TX 1500F (2 cylinder). The muffler is gone. I was quoted $700 for a replacement. I am fabricating an exhaust manifold with an up right muffler. I will take some pictures and see if I can figure out how to post them.
