S&S Mk45, Fuelmoto Jackpot Street Outlaws, S&S Grand National touring are three mufflers with removable torque inserts designed to allow for customizable torque “feeling” at low/mid rpm. Many threads you can review. Others will chime in as well I’m sure.
V&H twin slash will lose low end, ask me how I know, lol...

On to my second post, I am sorry if this seems a little spammy, I just didn't want to combine two different questions into one thread in case anyone in the world of the internet wants to search the same thing I am looking for, keep it nice and clean.

We just bought a 2020 Road Glide Special, I didn't realize how quiet they were stock (that was shocking to me - first brand new Harley) we are looking into getting the exhaust done. We live in CA which has strict laws on the exhaust that can be on bikes. We are going to go with Slip-on's as most are approved (from what I have found) and we don't have to worry too much about tickets and whatnot.

Harley recommends that we go with Khrome Werks, which I believe is their exclusive brand. After watching a few videos on youtube (the very few I could find) the sound just didn't seem that great compared to other exhausts out there (no offense to anyone that has them).

During my research I have found these as what may be the top exhausts available:

Rinehart Touring 4” Slip-On Mufflers
Vance & Hines Twin Slash Slip-on Mufflers
Arlen Ness MagnaFlow Redline Slip-on Mufflers

They all sounded good to me from videos (no live demonstrations) however, the Rinehart Touring 4” Slip-On Mufflers stood out the most.

Does anyone have any feedback or recommendations? We want to do it right the first time, so we don't have to change it again.

*Disclaimer: New to the Harley/exhaust world, so may not understand complex ideas.

No low end lost all, no popping, bike runs friggin great and sounds it too.
