Looking to go to a mandrel pypes system.

What would the ram air manifolds bring for improvement? Worth the effort if I can find them?

I've never tested between log manifolds and RA manifolds but I know some people have. Dennis would be a good one to ask.

From the dyno stuff I've seen these guys post like Dennis, I don't recall a huge difference between logs and RA manifolds as surprising as that may sound. I think the HP differences were in the single digits if I remember correctly.
