First of all, I've never purchased a new motorcycle before, and something that is really confusing me is when the 2015's will be available. Multiple articles I've read tell me they are available in "June." Is that June of 2014 or 2015? I would love some clarification on that.
Now, back to the main topic. I am going to finally pick up a new machine next year, whether it be a 2015 or 2016 depending on whats available at my dealer. The model year, however, is besides the point. Among lubricating the bearings and a multitude of other things that I want to do to it right off the bat, one of them is going to be installing a new exhaust system. The purpose of doing so is to make it louder, plain and simple. Extra power is always nice, but that is not as important considering the new Yamaha's capabilities already. I will be purchasing a full exhaust system though. I've been racing a 2007 YZ250F with a full FMF exhaust system for 5 years now. I'm an old school kind of guy, but it's time to move on. My bike can't take it anymore. I cannot, however, get used to the sound of the stock exhaust system on new bikes. I test rode a buddy of mine's 2014 for a full day and it is simply too quiet. I could write another three paragraphs on why it is that I can't race a bike that is this quiet, but I'm not going to waste any more of your time and I ask that you don't waste mine with your opinions on noise.
I've always thought that Akrapovic looked pretty sexy on Yamaha's. What's your favorite brand of exhaust, and why? What do you suggest?
Oh, and will I need to buy a power tuner for the ECU if all I want to do is add exhaust?

Anyways, wow, I actually didn't know that. I've had this exhaust system on my bike the entire time I've owned it, so I've never heard it stock. I think what I'm really getting at is the quality of the sound as well. If I just removed the silencer it would be loud, but an aftermarket system almost always sounds better in that department. I've heard the difference on quite a number of machines switching from stock exhaust without an insert or silencer to an aftermarket system also without an insert, and the aftermarket ones really blow the stock out of the water.
AKmotorider-During the time you've had your FMF system did you ever repack your muffler? If you didn't you left almost two horsepower on the table.
Good for you that you like louder bikes and I guess in Alaska you aren't concerned with annoying anyone. I would look at the 2014 pipe reviews and see which systems fit your type of riding and apply that towards your 2015 purchase. One way to make it louder (but lose mid range) would be to open the muffler and take a third of the packing out. With having that big of a void in the can it won't be long until the rest goes away.
Just run it stock... What's the point of dropping the coin on an exhaust if you are only going after sound, not performance?
I don't get it?
just wonder how often you notice the "quality" of the sound of your bike when you're riding it?
I can just imagine going down a straight and thinking 'damm my bike sounds shit to everybody'
maybe when I was 16
hahaha
You're right though on the Honda being fairly quiet stock.
Plus FMF has great customer service in my experience and have a support truck at many events throughout the year. One time Kyle Dangler repaired and new packing on my pipe at a race between motos.
FMF
One of the magazines tested a bunch of systems for the 14. The charts they showed made it pretty obvious that Yamaha had a great stock system. For sure i woudl wait to replace that specific one until it was needed. Heres what i saw...

I think there might be someone who coudl feel the difference, but its sure a lot of money for a maximum gain of .73 hp
Pit Row
With that said, I've run a few different exhausts (MRD, DR.D, PC, FMF) between KXFs and CRFs and have found that an FMF Factory 4.1 with Powerbomb header give the most grunty sound to get the juices flowing. Just pull all the dbl/spark arrestor inserts and it'll be loud enough.
