maybe the fitz one or i should see if the gt one bolts up and copy that if it works

First port of call i reckon. Also if you download cone layout it will give you the printable pattern. Then at least you can design the pipe for the exhaust duration you have.

Good to see strong progress on the smokers! If you want to be rough about it, you could try adding length and/or reducing length from the header of your pipe. This will likely correct/minimise some of the mismatch but it's a compromise over true potential power. A pipe built for the cylinder and purpose is the best way clearly.

Lol before the invention of the 2T expansion chamber by limbach and when two stroke trucks where the norm the length of the pipe is how you 'tuned' the engine.

When you bought a new 2t truck from the shop the asked what type of driving or terrain you operated on normally they cut the pipe to suit tuning it to your needs....Crazy stuff.

If your exhaust port duration is 194 then it should be bang on. The calculator spits out the same pipe if you put in the numbers. I just measured mine and it came up a little short. If you are making that pipe knock me you one would you. Cheers.

i was hoping you were going to make me one

Have the pipe here to try, do you nred the manifold?

i have the same manifold so should go straght on

Easy, was going to give it to uncle steamy yesterday but as usual, let me down....

I will totally make you one. I think I could loose you 4hp. maybe more. If I do you have to promise to run it.

Went into the dungeon and found a pipe I made 20ish years ago not far of fitzs
