Exhaust Flow Comparasion...

[forestbrian88]

Id like to know what is the diffence in flow between the stock 400ex Exhaust and the stock 450R(pre2006)
anyone has an idea?

The best exhaust for a 400ex is a cheap hollowed out shorty slipon and ground header welds.

Thanks for the tip Johndo83
but im not asking about what is the best or not... im just asking, compared to a 400ex, how does the 450R exhaust flows?
