I have the means of removing the cats on my bike to help relieve some of the heat that it gives off but have a couple of questions first to help me make the best decision. I read from a post that since the cats is after the o2 sensor i would not have to change the a/f or air/fuel mixture. Is this true? I know i could do a stage 1 on my bike but to honest i'm just not into the loud pipes anymore, just there for the ride. Is there any after market pipes that will let me lose some of the heat and still keep the sound low? That way i wouldn't have to alter the stock pipes just in case the law changes here in Georgia and they start checking for this. Thanks for any ideas you can provide.
