lol what makes you think I'm not in one of the police cars
If you guys are talking about certified street legal slip-on resonators then there never was any debate between us to begin with and more power to you, but I believe I made that clear from my first post in this thread "
Did you narrow your search to street legal ones? Might be wise." If your slip-on exhaust does not comply, well there you have it, you could be the guy on the signature bike, or the kid living down the street from Wingboy riding his daddy's bike.
"A slip on doesn't remove the cat so the emissions are changed how" Depends on the bike, if the slip-on modification obsoletes a servo controlled butterfly valve as it would in the one shown in this video, or exceeds the legal noise limit, then there is your answer:
... my MV Agusta F3 is an example of an EPA compliant exhaust that has no tailpipe resonator to begin with and it sounds and works freakin awesome, no way would I want to alter it just to be louder.
