Nobody knows? A 5" stack necked down to a 4" stack at the top. Would you calculate the lenght based on a 4" pipe, or a 5" pipe?
Or if nobody knows the answer to that, would it hurt to have a 5" stack that is about 150% of the lenght the calculator says? Maybe just make some way to just choke it down a little on top if needed?
He Mister, did you go to my house while ai was at work and grab my Willys Jeep Trailer
So. I guess everyone is probably thinking that I gave up on the build by now!
I have just been really busy. I have managed to get the ends cut. We have a plasma cutter at work! That is the way to go.
Then just yesterday, my father-in-law gave me a trailer to use!! Here are a few pics...
