Some will say you loose low end with out cats. I disagree. I hate cats!!! End of story. With a decent muffler you dont have to worry about drone, or rasp. The statement about the flowmaster having too much drone isnt fully accurate. My RC has a flowmaster and very little drone, my CC has a magnaflow and a hair more drone, neither are bothersome. My old RC had a bad drone at about 75mph, so I added a bullet as a resonator, cured ALL the drone and rasp. Right now, the only rasp I have is in my CC at WOT.

Best thing about going catless is you **** off all the ****** tree hugging hippies

 

 

Pacesetter LT's, ORY and Corsa sport cat back. ZERO drone at highway speeds.
