OK, I got her all broke in now, 2,000 miles and picked up some FMF carbon pipes.
very loud without the restrictors in and tolerable with them in.
still pretty rumbly but it does sound good.
the shape of the pipes really fits the bike well.
the biggest thing is the heat under the seat is much reduced, it was a real roaster before , especially with the 90 degree temps this time of year.
Now that it is broken in it runs much smoother and the suspension seem to be much better.
Pulls like a locomotive, one of the funnest bikes to ride I have ever owned.
