Ordered the S&S Grand Nationals from Fuel Moto along with a Power Vision license. I don't like loud and these should be on the quieter side. Ordered them without any info on performance. Or without hearing them. Not ideal. But all the others I have heard are on the loud side. Hoping there is no loss of bottom end power.

 

 

I have them on my heritage. I kept the DB reducers in. And love the sound not loud at cruising speed. Nice deep tone no poping sounds. And no tuner needed as per S&S.

 

I think they sound better with the baffles out but I would be concerned about losing low end torque in that configuration.
