RE: Screamin Demon w/West 50V1 with tuned pipe question
Just bend the pipe coupler some if all alse fails.
It doesn't hurt, except for the coupler blowing out after 200+ flights. If it blows earlier you have your pipe spaced too wide from your header anyway. That engine is not that hot.
Don't move the fins, there's no need to.
Get some proper silicone tubing for a coupler...don't skimp and use cheap stuff...it doesn't last...
