the 50 series is perfect if you are just looking for a nice deep tone without all the drama that the 40 brings all the time. You can barely hear it over stock at idle and it gets noticeable when you get on the throttle, not loud either while cruising the interstate. Where did you find it for 90 shipped?
I'm not telling you!!:lalala:
good looking out, glad i could help you with quandary.![]()
