I Have a 2000 SS w/ stock exhaust and I am planning on going the electric cutout route. Cant beat going from stealth to NASCAR in 10 seconds.

When I go to web sites and look at cutouts, seems like there are 50 to choose from( maybe not 50 )

My question, what size cut out do I get. (will Any size work)
Bigger= Louder? (Noticably?)

Also would there be a benifit with 2 electric cutouts? does anyone have this?

Get the 3" one. That's what I have and most other F-body owners out there. You'll love the sound! Good luck with it.

Just put a 3" in yesterday. Believe me...its loud enough.

I drive around with three 3" non-electric cutouts, always open

Can you say "overkill"?

No,but really did you happen to get your car dyno'd before and after?

Have you heard other cutout cars... Is yours much louder with 3?

where are they located?

Nope, true duals. They help with the exhaust side of the boost. I dynoed my car before and after the cutouts, but, ran into problems.

1 cutout by the rear: 10:1 A/F ratio on a wideband
All three open, the front two (one 2' after each header): 8:1 A/F ratio, maxed the wideband out on rich.

So, the hp numbers dropped until I tuned the car for 11.5:1 A/F, but I didn't compare before/after due to the tuning problems from the A/F.

To make a long story short, the cutouts sound badass, and picked up some SOTP after the tuning. But they also made my car seriously rich until then.
