Exhaust Stack

[TJ5208 1,824]

What angle of pipe do i need to have to have a exhaust system like this.

[JimSraj 430]

The iron pipe looks like a 22-1/2 and a 90 plus the nipples to connect.

What about the bend in the middle.

The 22½ is a female to female elbow - 45º (edited!)

Looks to be a 45º coupler

I want to do this setup on my Raider 14 and I like how the exhaust goes straight out not at a angle.

Also, it'll need a support bracket -- you cannot safely support that from the block only.

Note i edited my response. 22 ½, not 45.

I could make a support to the frame.

That’s the 22-1/2 if I’m looking at it right. Looks like a 3” nipple out of the block, then the 22-1/2, then a 2” nipple into a 90 into another 3” nipple to the muffler. 

Agree on additional support.

Is that a 45 degree angle?

[twisted metal 49]

Yes it's a 45 degree angle. They only make 45 and 90 degree threaded pipe fittings.

22-1/2 is half of 45, basic geometry.

[rmaynard 15,516]

I've never understood why someone would want a stack on a garden tractor. 

[wallfish 17,014]

This thread is confusing. Both the 22 1/2 thing and why anyone wants a stack. LoL

The exhaust port coming out of the Kohler engine is at 45 deg, That pipe nipple exiting the exhaust port goes into a 45 deg fitting, Then to a 90 deg fitting to turn it straight up

The angle the pic is taken might be at 22 1/2 deg

Yup 45° +45° =90° If you managed to find a 22 1/2 the pipe would come out at a funky angle towards the front corner of the hood. 

[Jeff-C175 7,202]

Just for completeness sake, the pipe thread is 1" IPS.

 

You can brace to frame as long as it's not a shaker plate.

[953 nut 55,324]

If you replace the 90 with a 1" X 1/2" X 1" black iron "T" and drill and tap a 1/2" pipe plug for 1/4-20 the brace can be put under the added weight.

[JimSraj 430]

Nice brace idea 💡 953nut!

If you want the stack a bit further back you could eliminate the short nipple and F X F 45 and use a 1" black iron Street 45 right off the engine.

Have you did this to your tractors? Do you have pics?

Would someone post some pics of there stacks on a 14 hp Kohler with the same setup as in post #1 or in post #19.

Just like the other pic I sent. Just a different tractor and a smaller muffler.
