Will it fit? If you did it would you do it again or go aftermarket?
Thanks, M.

I have one on my bike. I got it for $90 as a brand new take off from eBay, so I cant complain. Its def louder than the stock pipe, and it seems to run a little better after I loaded the YZ map. If you can find one cheap, do it! I picked one up to hold me over while I save for a titanium system.

The 14-16 YZ450 mufflers and pipes should fit right on. If you want it even better like a straight through perforated core with a spark arrestor just add a pro Moto billet end cap on the back.
