I've got my rear cats deleted just to hear what of an difference of a sound it would make... All i can is it makes a big difference and now at every light someone wants to race..(I don't) but it does makes it sound totally different, and louder. This is just an video of an cold start-up on idle. It was a little above 32º outside so the smoke you see its not the valve stems seals that needs to be replace. Let me know what you think. (Just donated to the .net also, its been slipping my mind but finally got around to it)

Keep them in. When I hacked off the rear cats with res-delete tips, the exhaust took on a very raspy annoying sound. The sound you have now is perfect.
