Newbie question here, but I was reading online about V&H Big Radius 2-2 pipes, and came across a comment that I'd like clarification on. The poster stated that- "The big radius pipes DO NOT have the power chamber in them. All the V&H pipes we have tested without the power chambers perform porly. IMO they are just for looks. Really big pipes usually perform really bad on a sporty.'' Can anybody shed any light on this comment?
