I agree with alien, i honestly don't think the BR are loud. I love the look and the pipes and they are diff louder than stock but i could go for something louder but i like the look and what i got.
It seems quieter when you are riding with them, but when I was behind you Spyder, they seemed pretty loud when you gunned it!
I really like the look of the BR pipes and I do like the low growl they put out.
I also like the fact that I can be somewhat quiet if I need to be (neighbors, horses & cops...) or the fact that I can open them up a bit and get a little volume out of em.
I ride with a few guys that have Samson, Yaffee X-Pipes and even Cycle Shack slip ons' and it's hard to tell if my bike is even running.
Have them on my 08 SG. I love them. you can control the sound very easily. Full out it is loud, but once you get up to up to speed you can hear the radio just find.
