I would like to get a straight pipe for my 1955 WD-45. Does anyone know where I could buy one? I have always been told that a straight pipe will damage a motor but I have also heard that it wont hurt the motor a bit. I would appreciate any help.

For awhile I had a straight pipe on my WC...
It got very annoying while mowing so I went back to a muffler.
I like my hearing a lot more than the sound of an unmuffled AC.

We have a glasspack on ours and it runs just fine, sounds cool too, sounds like a big pulling tractor...

I like to use stainless milk line pipe. It looks nice and wont rust It also has a better sound than a regular piece of pipe.

A certain size of electric conduit will fit, well it fit the new manifold I bought anyway. Then weld on a bracket to bolt it to the manifold. It might sound good, but after listening to it for a while are you sure you don't want a muffler?

I would run striaght pipe if I had a WD 45. But all I have is a "C" and I have straight pipe on it!

Don't put chrome pipe on it because it will turn different colors after it heats up and cools down! You dont really need chrome pipe if it isn't a show tractor.

Ahhh, but you CAN install a Chrome pipe. You just don't use it for your main exhaust pipe. I have a straight pipe on my B, and it seems to run fine. I also have a chrome stack pipe which I slid over the "real" exhaust pipe which is in the manifold like the OEM muffler slides in. The chrome stack I have on the outside which is held in with the bolt which threads into the manifold. The bolt serves two purposes. Holds the chrome pipe and snugs up against the inner exhaust pipe to keep that tight also. I did that revision about 2 years ago, and they are both still nice n' tight. Best part about it is.. no colors in the chrome!
I guess it's just the "hotrodder" comin' out in me... LOL!

Steve,

I know what your talking about when you put the chrome stack over the OEM exhaust pipe. I have a friend that did that to his B. It looks sharp. Im thinking about doing it to my C! What size chrome pipe do you have? I have a 1.5" diameter straight pipe on the tractor!

I just didn't want Martin to go and buy a chrome pipe and then be upset because it turned colors and we didn't tell him!

Hi Eric!

If memory serves me correctly, I believe I used a 2.5" chrome pipe to cover the 1.5" exhaust pipe. This gave it some air space in between the pipes. It worked out pretty nice. One of the fellows mentioned a glass pack. That was the next thing I was working on and putting a 3" chrome pipe over that to give it a better sound....

Cut one out of an old driveshaft tube, and weld a bracket on it...!!

Dad ran his for 20+ years with a straight pipe and it never hurt it..I ran a muffler...they both pulled the same..4-14" semi-mounted plows in ANYTHING...7" Deep.. You could always see when he got to the far end of the field..( A Half-Mile away)-- there would be a 3 to 4 ft flame rise up from that pipe when he closed the throttle, as the plow came out of the ground...!! A 6" BLUE Ball of flame would be over-top of the pipe, anytime it was running at full throttle..!! Made it easy for him to light his cigars..!!
