Full Akrapovic exhaust System?

Im having a terrible time finding a full akrapovic exhaust system for my 2009 WR450f. Just wondering if anyone can help me out? I have my heart set on it because of the possible 6 hp gain i can get at the top end. (according to their dyno test). I am open to suggestions for other brands too. I just NEED more POWER! thanks

Are these systems worth the money if all you have is free mods?

I assume by "full system" the OP means header and muffler. None of these appear to have the header.

To the OP, you know you can mod the stock exhaust and get pretty decent gains, right? I did this and the gains were more noticeable than all the other free mods combined IMO, and I still have a spark arrester and am under 99 db.

I left my stock muffler, took out the skinny insert now it wheelies with me leaning forward trying to keep it down. Before it would barely try to lift it 1st

You can also drill holes through the internal baffles or take them out completely. I drilled three 1/2" holes through my baffles and the difference was amazing. Taking the baffles out completely would probably do more, but your exhaust would be super loud which is usually not a good thing. With the drilling method you can drill one hole at a time and ride it and keep drilling and riding until you find the best compromise between performance and sound.

How loud is it with the holes? I took out the peashooter and it got a lot louder, enough to get pulled over for maybe

I don't know if I could buy an Akrapovic exhaust system for any of my dirt bikes. I'd cry the first time it hit the dirt.

More like artwork than an exhaust system.

By full system i did mean header too. i actually did find a place that could bring it in but for $1100 bucks i don't think so. I had my stock exhaust uncorked before i picked it up from the dealer. I have been away from my bike for a while due to work so i still have to do the AIS removal. I also have a JD jet kit and a stock YZf exhaust i can put on. I'm Hoping these will make a significant difference because i can't pop this bike up past 3rd gear.

kwinn......sent you a PM. check it out.
