first of all I'm not a owner yet, the wife said i can oder in November. but was wondering if anyone has taken there catalytic converter off yet for more horsepower. and if so could you tell a difference. i know most people live where you can't take them off , but i live in the great state of South Carolina. where motorcycles don't have emission laws. most harley owners run straight pipes. for the sound and extra power.taking the converter off would be something i would look into if it had a benefit of extra power. i don't think i would run straight pipes. to loud for me.
