What kind are you looking for? There are 3 that I know of. There's the old type that have wing nuts and you unscrew them and pop off the cap. Then there's the manual valve type that have a lever you can run up into the interior and open them from in the car. And then there are the electronic ones which open from a button inside.
You can find the manual ones in Summit's catalogue but I think you have to go straight to some of the vendors for the electric ones. Do a search on cutouts and you should find the vender. If not, I'll search for their website when I get back home next week.
BTW, I'm also considering doing this and will probably go with the manual type that have a cable that runs to the interior.
I know the electric ones are like 300 bucks or so. Mainly I am wanting to see if anyone locally has done it. what is looks like? tranny heating issues? sound?
I'd also like to hear what one of the newer vettes sounds like with open exhaust. After my latest engine swap I was running open headers for a few days and it sounded meaner than hell. Let me know if you find anyone with them, I'd like to hear them.
