I have a 2004 yz450 that is basically stock besides renthal handlebars, sprockets, and a DID chain. Im looking to upgrade the intake and exhaust and I am already planning to buy a K&N filter and jet kit unless i can find something better but what I had a question on was the exhaust. Im not sure what kind to get. I would like something that gives increased horsepower over the entire RPM range. Any suggestions about the intake or exhaust would be greatly appreciated. Thanks :thumbsup:

Dr. D - Great pipe which gives more over rev than stock. It consistantly gets great reviews from the mags and thier customer service is top notch. Dr D has spent his life on Yami's and no one knows them better.

I have the FMF 4 Ti. I think it is great. It smoothed out the power band. I highly recommend it.

White Bros Carbon Pro. It smooths/evens out the power, is the lightest system available, and looks super trick. This is also the system Factory Yamaha is running right now outdoors. I am going to sell mine, $600, as I am scheduled for ACL reconstruct and probably won't be riding for a long time.

PM if you're interested.

White brothers carbon pro all the way. I have had both the jardine and the fmf and feel like the carbon pro is the best. Just a tad on the pricey side. Cheers!

i had a white bros R4 it was nice, but realy loud and that is what is shuting down all our riding areas is loud pipes, it sucks but i had to get a differnt pipe to keep the noise down, this is something you may want to look at in your state to see if the dnr has noise restrictions. i now have a yoshimura RS3 Ti muffler with a gytr stainless head pipe good power, but i can make it quieter with the tec kit they offer, it has a 96db and a 93db insert. i am running the 96.
i have hear from many people that the fmf Q is also a good pipe in that they keep the noise down to 96db, i know of several people running these. you may want to check out ebay, thats how i got my yoshi and head pipe. for less than 300 bucks.

id go to www.dirtrider.com and check out there product reviews ... i think they are for 2003 but they will give you a general idea on what your looking at i suppose !
if you have the money go titanium but stainless steel is good as well ! white bros or Jardine is my vote !

I have the FMF Powerbomb header pipe, and the FMF Q muffler. It sounds loud as heck when you are on it, but I was following my bike the other day when a buddy of mine was riding it, and it is actually pretty quiet. My buddy is an ex team usa rider in the 7 days enduro, so he was giving it hell.

White Bros Aluminum Race Series is the same pipe as the carbon pro - just that the canister is aluminum - more crash worthy than carbon fiber & less expensive. ... around 550 new - best pipe that I have used on my 450

They stopped making them, but if you can still find one get the white bros. R-4. They rated one of the best slip on's in Dirt Rider's '03 pipe shoot out, and the least expensive. If you cant't find one then go with Dr. D.
