    I've got an 07 GT500 and I just bought KR500 mufflers and running them with an off road x-pipe. It's pretty loud without CATS. I love the sound but i'm not sure I want to take the chance of getting pulled over.

    Is anyone running high flow cats with either an x-pipe or h-pipe?

    I'm just wondering if they still sound LOUD. I'm actually contemplating putting the stock cats back on.

    thanks
