Got bored this weekend and took the cats off my Bassani x-pipe. I had not heard one without cats before and WOH BABY does it sound different...much louder and gnarlier sounding. I scared the crap outta some kid in a rice POS that sounded like a bee in a tin can...he decided maybe he didn't want to run with me after all... I love the sound, but now I'm paranoid that the noise gestapo is going to pull me over.
