K301 straight pipe

Brianjbell · Nov 4, 2021

All, I have a K301 on a CC 124 that I'm building as a puller for my boys. I'm looking to install a straight pipe on it and noticed that it doesn't have the bolt holes drilled and tapped for the MidWest SC flange for straight pipe installation. Wondering if anyone else has come across this and how you addressed it. Should I just get a straight pipe nipple from Lowe's and go that route?

That may be your best alternative since you can't bolt a flange to the block. You will probably have to add a brace to support it if you plan on turning it upward, the pipe threads tend to loosen up when the engine gets hot.

You can add a lock ring to the nipple that screws into the block and that will. Help it stay tight.

I took the stock pipe and flange off . To much restrictions.
Bought a torque tube kit from Robertson .
Now if you do this I you must wear ear plugs. , decibels between 110 120 ,
