For those of you with them, when do you open them? would it be bad to have one open during daily driving? and what kind of power increases do you get with them?

Thanks

it is not bad too run with them open, I used to leave mine open all the time until I got the elec.part for it. You will notice a power increase at higher rpm's, now that they are elec. I leave them closed until a ricer pulls up and pisses off his bumble bee then I flip the switch and let him have the lovely sound of a V-8.

 

the question is when do i close it.
