catalytic converters do I need them?

When I first put headers on my car I also had the secondary bypasses so no cats. The throttle response was noticeably improved but the sound was horrible. I have the PSE on my car and it had always produced a great growl at RPM's. Without the cats, the sound was higher pitched and raspy. I slunk down in my seat it sounded so bad though others really liked it. I tripped a cel about every 300-500 miles. I put the secondary cats back on. I little less HP but much better sound.
