Tuned exhaust

[Glenn5ft19]

Hi,
I am building a WAG PA18. and I just bought an O320. Since it's it experimental and needs an exhaust system I figured I would build one. Does anybody know where I might find the required lengths and diameters for a Tuned exhaust for that engine.
Thanks
Glenn

Glenn,
I asked the same question a couple of weeks ago. I was looking for information concerning my engine. Here is the link, Tuned exhaust? it may help.

Have fun!

Tuned Exhaust

Hi Glenn
Check out Burns Stainless and Sky Dynamics both have some good stuff.Burns will run numbers if you fill out an on-line info sheet.I think you will find that the ideal pipe length cannot be accomodated and you will end up with 38"-44" primaries.You may also want to look at how Powerflow builds their primary system it looks like a good way to build a system for a cub with a Lycoming.
