These pipes cost more new than the engine cost new
Unless you can find a used pipe at a good price, they are not cost effective.
Pipe= $85
Header= $29.99
New HB.61 PDP= $187.00
Granted, I could just purchase a new Magnum, but I already own a HB. 61 PDP. To me cost effective would be to purchase the pipe and header verses the new engine, pipe, and header. (I have a new Magnum I am mounting a pipe to already in another aircraft.)
If Jett offered their tuned muffler to fit this engine, I'd probably go that route.
Also, Mecoa offers a header and tuned pipe. I believe the header is around $30, and the pipe is $65.
Having limited experience with engines and tuned pipes, I'm simply trying to gather information before I purchase. This is the route I prefer because this is the route the classic pattern ships went.
