From what I hear Big Gun is releasing a Dowd system that is supposed to really rock. Since I have neither a Big Gun exhaust not a RFS to put it on I can not say it the claims are true. Dowdy sure did pull some monster holeshots last year though.

why?

Why change the exhaust on a520?
Dowds system actually de tunes the motor making the initial hit less and more controllable.He has since gone back to the stock system.
Unless you are looking to loose weight there is not any benifit only
money out of pocket that could be spent on tires and the like.
Also the Big Gun systems do not fit very good and some bikes have had problems with the clearance btween pipe and shock.They have also been
melting plastic.
The bike will be much louder. As much power as the 520 makes there is no need to have more.
