I have a 2002 firebird WS6. I just wanted to share this for those looking for a stealthy exhaust that can readily be turned into a wild, loud, who cares about neighbors sound.
First if you like being loud, like to wake up your neighbors at 5 am when you turn on your car then this is not for you. Where I live we get tickets for having a loud exhaust. Therefore, to get the best of both worlds I did this. (Look at picture attached). It's a Borla catback with a QTP 3" electric cutout in place of where the plates go. It was direct bolt on no welding. So with the flip of a switch I can go stealthy/wild. Mind you my car has long tubes/ heads/cam and when I close the cutout and it reroutes fumes to muffler it's very quite. I will come back and add videos of the difference.
1/6/2017 Update** Ok I'm back with videos and yes as Cody pointed out, the first picture is an old set up mine is the updated one specific for the 02 model.
First Video cutout open full
second one cutout is closed completely therefore routing all exhaust to one side and decreasing the sound substantially.
Although I like it so far I do want to try Texas Speed's new catback that has the 4" cutout towards the middle of the car.

Oh no! I didn't mean it as a discovery. I actually got the idea from our wonderful forum site. I just never found audio clips and that's what I was going to do. Just need a couple days to upload videos
