post some pics. I had no idea that bgf was offering an expansion chamber.
In the world of chambers, the phrase "you get what you pay for" applies.
sure, a chrome one would be cool, but does it perform? The sbp one has proven results with many people here.
I have never heard anyone mention a bgf chamber until now.
and you do need a muffler on a chamber.
the muffler will actually make it produce more low end power.
I have an all chrome chamber from spooky tooth which looks cool, but it really doesn't give much of a performance gain because of the way it's designed. granted, it's better than the stock pipe & muffler, but it's more for looks than performance in my opinion.
if you look at the sbp chamber, it resembles a proven 2 stroke dirt bike pipe and it's tuneable to your liking.
sbp has put a lot of research and tuning into their pipes, and they perform very well.
THAT's why it's $70.00 and not $50.00.
I want to see this bgf chamber tho.
**EDIT**
I just looked up the bgf chamber and come to find out, it's the same design as the spooky tooth chamber (same as the one i have).
in my opinion, you will get more performance out of the sbp chamber than the bgf chamber. The bgf style chamber does add a little power, but not much over the stock puipe & muffler.
if you go with the bgf chamber, you will want a muffler on it because it is annoyingly loud (I love straight pipes, and open exhaust) but this thing is just annoying, it doesn't even sound cool without a muffler. I modified the stock muffler to go onto my chamber, so it's still loud and has a good sound, but it's not so loud that it's annoying.
