3525 Exhaust Conversion

[TexBran3]

Howdy,
I have a 3525 that is a couple of years old. I am going to change the exhaust to come out through the hood. I bought the manifold, gaskets and exhaust stack already. I was wondering if anyone has done this? Any ideas of where to get a muffler? I don't recall the exhaust stack diameter.
I am doing this because an' ol' boy I know caught his hay field on fire last year raking hay. The bottom rear exhaust has got to go!
Thanx,
Rick

Tex,

I'm very interested in how your conversion turns out... I don't really like the rear exhaust either... I'd rather have a conventional vertical exhaust.

Would it be possible to use the original muffler? You might have to have the inlet flared so that it can slip over the stub on the manifold... that would be the easiest way to remove the muffler to open the hood.

Keep us posted!!

Brian,
Thanx for the reply. The origional muffler has brackets welded on it so they would have to be removed before I could use it but it is a possibility. This has become a "winter project" for me so I will get to it soon......I hope. The ol' boy I knew that changed his around just runs a straight pipe but it is too loud for me.
Thanx again,
Rick

I would really like to hear how this turns out for you. My tractor got stuck in the mud and while trying to get it out the "resonator" and some of the exhaust pipe was ripped off. The muffler is still there but after seeing what happening I couldn't understand why in the world it would be designed like it was.

Any place you put the exaust piping, it will have some draw backs when doing some type of application.

Perhaps a look at a 3325 would give you some ideas. Its basically the same tractor with vertical exhaust.

If it weren't for all the mesquite trees I have, I'd probably prefer the hood mounted exhaust stack. The only thing I don't like about the rear exhaust is having to breathe it when adjusting attachments or digging post holes.

Exactly... hooking up an implement and breathing the fumes is the biggest negative for the rear exhaust... although, I've almost torn mine off clearing brush already too. I got it all straightened out again for the most point, but, I wouldn't have had that problem (either problem) with a vertical exhaust.

Yes Sir. Having to breathe the exhaust while hooking up implements is another drawback to the rear exhaust. Like I said earlier, an ol' boy I know has already done his and he likes it. His is an older model and had a hole already in his hood covered by a large rubber grommett type deal. The only thing holding me back is having to cut a hole in the hood for the muffler stack and finding the right muffler. Not sure how I want to cut the opening in the hood. Any ideas? I already have the manifold, exhaust stack, bolts and gaskets. Not sure what the Galen means about exhaust pipe problems. Maybe he can expand on that because it looks very straight forward. Change out the exhaust manifold and bolt the exhaust stack on top of the manifold and bring the muffler straight up thru the hood.
Thanx for all the info.

Not sure what the Galen means about exhaust pipe problems.

I think what he meant is regardless of where the exhaust is placed someone is going to be complaining about it's location. If they are up top they complain about blowing back in your face, if it's out the side of the engine (i.e. 5525) they complain about the possible heat on their right leg, and if it's out the back they complain about it hitting stuff or exhaust in their face.
