Get the Q4 if you need one. Its quiet, which is a good thing.

If you can find a good conditon OEM pipe you will be set.
I dont care what anyone says. The fit and finish of a OEM pipe is worlds better than aftermarket pipes.
a 03 04 and 05 pipe will jump right on. No need for a header as you have a nice and light Ti header that comes stock.[/COLOR]

thats what i was hopeing you guys would say, but one more question, should i get a megabomb or powerbomb header?
Neither one. You will not notice the difference. I have a titanium megabomb header in my garage that I never put back on after I dented it. (Its very soft btw) I have nicely dented titanium FMF pipe and header that I had had to get repaird several times. Never any damage to the stock. Its a little heavier. But if you wanted a lightweight bike, you should not be riding a wr450.
If your money is burning a hole in your pocket and you have to buy something, I would buy a muffler before the header. I have an 05, so I was able to open up my exhaust and let it breathe quite a bit. Get one of those and save yourself a ton of money. The FMF will look cooler for sure, but you won't go any faster after you spend the $400 bucks.
If you want real performance upgrades, take the exhaust/header money and buy some cams. Then get all the accessories to dial in the carb. That was money well spent after I wasted $800 on exhausts.

I found a 2003 YZ450F muffle and midpipe in the classifieds here at TT for $50, he pulled it off right away when he got the bike and got aftermarket exhaust.
Now I'd ride someone else's bike fitted with an aftermarket exhaust before I considered buying one if I were you.
I bet you stick with your $50 YZ system!

Here is what you need.
One problem with it though, it doesnt have a spark arrester, and i dont know which kind to get and where to find one, any help?
I suspect you'll have to rejet with the yz exhaust. Just do all the free mods and check the jetting guide and you'll be fine. The yz exhaust is free flowing, but a bit noisy.
