Curious if anyone here has done this. Seems like a simple mod that can be reversed if the sound is not to your liking.
Why not just unplug the flaps on exhaust for free? Save yourself $200
I'm currently doing the unplug method 😝 I'll most likely get a muffler soon. But electronically opening/closing the valves on demand may also be a good option for others 😇
