I just hate the sound that stock makes and thinking about upgrading the exhaust.

1. Is used one is good idea?
2. How can I find whether my exhaust has O2 sensor on it or not??
3. Is the exhaust easy to mount by myself? I know there will be a procedure in service manual, I am just asking in case if there are any tricks involved!
4. Do I need to check anything after installation like tuning and smthing like that?
5. Do i need to be afraid of cops?

Thanx in advance!

1. used doesnt matter unless if its damaged or scratched...even then its preference
2. only CA bikes has o2 sensor
3. 99.9% of slip ons out there are bolt on
4. you dont need tuning unless if youre going full system
5. depends on what pipe and what state youre in
