"anyone know where you buy those cut out split dumps in 3 inch, electrical preferably"

do a search on google for "exhaust control valve"

 

no thats not what i am looking for i am looking for the y pipe that closes one side leading to the atmosphere and the other to the cat-back exhaust

 

yea thats what I was looking for, then I realized how you could make that work, you weld up a a y-pipe and cap off one end with the ECV and when you open the ECV, while it wont close the rest of the exhaust, (unless you rig up 2 opposing ones to the same arm) the exhaust in theory should be like elec and take the path of least resistance

 

but won't there still be a leak/noise coming out of there, those don't look to completely seal

 

you're not talkin about the exhaust valve? I thought you pop it on the bottom of the dp and put a pipe going where you want. Or you could put it on the top and have it venting out the hood(probably not good). That's not what you're talking about?

 

i am looking for the y pipe electric bypass thing

 

it probably would have some leak/noise, I dont know how well they seal, if its like a true TB and its an oval plate rather than a round one than it might

 

my other idea was to take one of the manual y pipe ones and removing the cable and attaching a small servo to opperate the actuator

 

they make that already, ive seen a couple f-body guys with those.

 

the only ones similar to those Ive seen are not the whle y pipe, if anyone knows of a link please tell me
