I just bought my full yoshi race and want to know what to expect when I install it. What jetting are you guys running I also bought a pro flow kit. How does this set up compare to the other full exhausts that you have raced against. Is it a really loud pipe? Thanks

I have it. It's a really nice pipe, and as far as I'm concerned, it's worth the cost. Not as loud as some, and the quality is out of this world. Bolt up is a piece of cake. I put the spark arrestor core in mine for legality issues. Didn't noticably cut down on power output, which incidentally is a very good improvement. Much better throttle response. Jetting at 165/170, needles raised one notch, pilots at 27.5 works well. Hope you enjoy it.

I've got one too... not enough time to give exact performance details, but can vouch for the quality of it. I'm not sure I'll keep my Raptor long enough to ever really know either. There is another post on here regarding Raptor pipes. I give some pretty good details about pipe diameter and so forth if you are interested in comparing them to stock or another pipe.
