These Grand National Slip-On Mufflers woke up my Fat Bob with more power and a deep rumble, but mounting them was tricky so I gave them 4 stars.

These Grand National Slip-On Mufflers are awesome, I put them on my bike and they sound so good with that deep rumbling sound, shipping was a little slow but they arrived in great shape and were easy to install, for the price you can’t beat the quality I’m really happy with how they improved the performance of my ride.
