Nice deep grumble

Absolutely beautiful, was looking for something to give some depth and life to my bike and these nailed. Not obnoxiously loud but a nice deep grumble.

Fits perfectly. Excellent


Would recommend.

By   on  Verified Purchaser

Quality product, easy install & look great! Only minor thing is the color finish is slightly duller than the factory black but for me that's not a deal breaker.

Does my 2023 Street glide special 114cc ..need to be tuned with these slip ons

Typically no, there is not any tuning that needs to be done for just the installation of slip-ons.
