Awesome sound !
Gotta remove de DB-killer ! Great deep sound, and just loud enough. You can ride for long hours without being anoyed. And when you open the trottle, that sound is there for shure !
Big difference compared to originals, very satisfied !

More power and more loud!
I bought the matte black S&S Cycle Grand National Slip-On Mufflers for my 2015 HD Street Bob. Easy to install at home, after I finally got my my mufflers off. Just slip-on and tighten the muffler mount and 2 clamps. I think they are loud with the stock baffles installed, I saw videos where you can remove the baffles to make it even louder but I think they sound great as stock.

I purchased 4," grand national pipes and they are fantastic. Absolutely no regrets. Relatively quiet when of the throttle and make enough noise when on it. Could not be happier

Questions
Do they turn blue with use?? Do you notice power gains after installation??
No discoloration, slight power gain, sound good.....not too noisy unless you are into throttle.

Not required unless you go with a full exhaust system or you change your air box from stock.
