I have a cat on my car #05732 but when it took it to Rob for it's first 200 point check back in 1998 it was discovered that it was hollow. We don't have smog testing here in Maine so my options were to replace it or leave it along. I choose not to spend the money and have left it as it. How it got hollow? I don't know. It looks stock but isn't doing anything. Not sure if I'm getting any backpressure from it being hollow???? __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
