Common questions
Will this Big Radius system fit my 2016 or older Harley?
No, this Vance & Hines Big Radius system is specifically designed for 2017-2022 Harley-Davidson Milwaukee-Eight models. Older bikes use different header and mount geometry, so it will not fit.
Is this exhaust legal in all 50 states?
This Vance & Hines Big Radius system is 49-state emissions compliant. Buyers in California should verify local emissions regulations before purchasing.
Do I need a fuel tuner with this full exhaust system?
Installing a full exhaust system often changes the engine's air-fuel ratio. A fuel-air module or tuner is recommended to optimize performance, prevent lean conditions, and ensure your engine runs efficiently.

Not obnoxious, but deliberate.
These pipes have come a long way since the legacy version I had on my Springer. Not obnoxious, but meaningful. I was after sound more than performance and got what I wanted.
