Question on Header evac tubes/check valves
I am considering adding the evac tubes to my headers with the check valves, etc. I am running mufflers. Is it true that if you run mufflers, the venturi effect wont work well enough for the evac tubes to be effective? I was told this is only good with with straight open headers and that evac would be minimal with muffers because of the back pressure.
Let me know your thoughts...
Thanks!
