I would like to replace this poorly made exhaust pipe in our 1915 roadster for one that's not squeezed at the bend. I figure I am loosing 30% or more flow thru because of this. The last exhaust pipe I purchased from a major parts supplier a dozen years ago for our speedster looked exactly like the one in the photo. I was hoping to find one with a bend not a "squeeze".
Talk to Larry Smith.
Pic of Larry's pipe, think you'll love it. You may have to buy it from one of the suppliers, as Larry may have sold them all "wholesale."
I cut it add 45* Mandel bent exhaust tube
To reduce restriction, you can use a FO-11 tractor muffler in place of the stock one. These are available from your friendly local farm store -- Tractor Supply or similar.
The repo I got maybe 12-14 years ago is nothing like that with the big kink in it. I think mine came from Lang's. I wonder if it was the one particular supplier that sold pipes like that.
The one you bought is the "usual part" most of the suppliers have; however, at least one of them will have, or now does have, a small supply of Larry's pipes. Not only are they not restrictive, they actually fit! Hopefully Larry will pipe in here (pun intended) with where to go to get one.
Ok when I am wrong I let everyone know! I just went out and looked at my exhaust pipe (was checking something else), it does have the kink in it. I just have never noticed it before. I have never really noticed lack of power or speed being held back because of it. If anything that might be holding it back is the piece of water pipe I used for the inner tube but it has lots of holes drilled in it or the early cast iron end pieces on the muffler with the brass toilet overflow tube tail pipe.
I've got several on a pallet to go to Langs. I rather be working on my '13 roadster!
