If stage1 swept are too loud, then Slash-ness are way too loud.
Actually the swept with factory baffles is pretty tame. My buddy had the Swept on his 09 Kingpin and I had Slash-ness.Mine was way louder.Then he pulled his baffles and his was still a little queiter than mine.His then sounded bad with no baffles in my opinion. I added Big City Thunder Baffles to mine and it was a little bit quieter, but still too loud for me. I ended up with a 2-1 from RPW and am happy now. Nice rumble in the lower rpm band, but deep and throaty when you get on it.
