I have the radius on my 04 springer with a wimmer in take. After dyno got 76 hp and 83 fb of tq
The guys I ride with say there load, but I can stell hear there bikes.

 

BIG RADIUS IS THE WINNER. Purchased the BR pipes and SERT yesterday and they are on the hold shelf for next week's appointment. The performance issues seem to be minor and there are many satisfied users out there with BR pipes. My Fatty has all the juice I want and to give up a few horses for that cool look and more sound is worth it in my book. Daytona (my first) taught me that every bike that's anything has pipes. I will post pics after the install. Usual thanks to this great group. Ed

 

Did you need/have a Power Commander or simlar tune?
