I've been talking with Nelson Muffler Co....

That muffler won't fit if you do a"restoration"

Price of the round Nelson mufflers for a D-17?

The WD45 gas & diesel and early D17 Nelson mufflers are still available. This muffler (pn 229531) fits WD45 gas/diesel tractors and D17 gas tractor up to serial #24001. I sell this muffler for $135 + shipping. Like Pat said another member Rick Corder has them also. Rick is in Missouri, I am in Wisconsin, so Rick would be closer to you in KS.

Alex, is that muffler for the WD45/D17 straight thru and blocked/baffled? Just wondering because I have seen them both ways just don't remember what brands they were.

That is a 180/185 muffler.

THE NELSON MUFFLERS ARE COMING!!!

I decided to go with mufflers for the late D17 gas tractors ser#42000+. These are the original style with offset outlet. The 3rd pic in JC(WI)'s post on the first page shows what these mufflers will look like. Dr Allis's post above states the dimensions. And, wait it gets better! My estimated price above was $200 per muffler, but these will be only $157 per muffler!!!!!!! :) I will post an add in the classifieds with more details for those who want these for their D17 gassers.

I would like to thank those who responded and voiced their opinions. Getting that input helped me to decide in what direction I will go with these mufflers. This run will be the D17 oval gas muffler only. If this goes well, I would like to order another Nelson muffler run for a different model tractor, perhaps the D15 or D17 diesel muffler or the 170/175 gas muffler (which is slightly different than this D17 one). Please give me your feedback on which Nelson muffler I should try next!

Sabre saw with a metal blade.

That sounds a little barbaric IMO Cry

. A little like a square peg into a round hole ??

I wouldn't. Would be like the guys blasting 10 inch holes in their diesel pick-up truck beds behind the cab to I "guess" look cool. Again, JMO. I must admit though, what is "wrong" with the available round muffler ??

I'd prolly make a good template, and use a sheet metal nibbler, them hoods is right thick... Wink

Our early 17 has an oval muffler. I'll ask dad if gramp cut the hole or who did. Guess the governor went screwy and over revved and broke crank. Both my gramp and great uncle aren't with us anymore so I can't ask how it exactly happened. It was back when allis was still, and gramp got a new engine from allis which made it a latter exhaust manifold.

Alex, what happened to your first diagram picture?

Was kinda hoping the 170 would have been the chosen muffler and the height of the exhaust pipe could be cut off to desired length. But a fellow could slip another pipe over if he really wanted to get the ex. up higher.

Lonn, I wouldn't use a torch, that would warp the metal... but a plasma cutter would maybe do the job in a sweet order, providin the hand is steady. LOL

The 170/175 muffler outlet is not only longer, but it is larger in diameter over the D-17 S-3/4 muffler.

JC- I deleted my sketched drawings because I had used measurements off the stanley mufflers and they are not the same as the Nelson measurements.

Although I didn't choose the 170/175 gas muffler for this run, I am leaning toward ordering that one next, unless a different muffler would be in higher demand.

But yet my question pertaining to the OP'S topic (thanks DR for the round/oval muffler decibles) is WHY the need for the NELSON MUFFLER ????
