Besides looking way cool will the addition of an FMF header do anything for my 650L? (already uncorked and running a FMF Q2)

I have a Q2 on my uncorked 650R - I'm not an exhaust expert, but here's what I learned.

In conjunction with the Q2, will lower noise about 1 DB (according to a guy I talked to at FMF).

Will increase the top end slightly at the cost of slight reduction in bottom end. I liked the noise reduction theory, but I'm a woods rider and like my stump pulling bottom end the way it is!

thats impressive that a bigger head pipe can reduce noise.
