Hi
Been reading and searching through the forum for the Golf Tee Mod.
Have seen different reviews on how it affects the sound of the Drone coming out from the exhaust.
I decided to do one myself to see. All I can say:
More drone on low revs and starting from stop. Sounds like I got an aftermarket exhaust.
I believe the butterfly valve is just a sound suppressor and will not affect your mileage or power loss/gain.
Love the droning and bevefing sound and will keep it that way until I need a louder exhaust.
