Bad news........talked to the tech who had trouble with the first V's baffles rattling, so he called Bowling Green and found out there has to be a certain minimum pressure in the vacuum line from the headers to the baffle at the exit of the exhaust to keep them from rattling, usually while idling. There is some sort of set-screw or adjustment that can be made to these line at the headers.
If the vacuum line can be cut and re-worked into an electrical open & close switch installed in the cabin, we could control what we want the baffles to do.
Got any ideas?
sure, plug the vacume lines.
with no vacume, they remain open.
I don't need to control them, I just want them to stay open!
If they rattle....take 'em out.
....and if that dosen't do the trick....move on to the Borlas
I just think there's an electrical relay involved at the origin of the vacume line, and a simple fuse pull and/or switch would make this a whole lot easier.
I'll do more research with the Z06 guys. I can't imagine that their system is designed any differently....they must also have vacume lines at the tail pipes, since you can't put electrical components there.......yet they're picking up electrical control.
I think the tec you talked to, while trouble shooting a similar issue, didn't really address what we're after here.
