The husaberg after market header is out of the way in a good spot but it's $700 plus. It's made of titanium I think. On another post someone had problems with this Header but was able to fix it easy. Something like 2 hose clamps and 2 springs before he did it he had a leak. Clamps on both pipes and springs to keep them together.

Isn't the Husaberg factory header made by Akrapovic?

My vote is for the FMF powerbomb. I think it's the best looking header, especially in titanium. Plus it comes with a mid pipe, which is the most restrictive part of the stock exhaust.

I was able to pick up one for a pretty decent price from a website that sold 4x4 truck parts mostly. Also it fits the stock muffler with no modifications.

So what is this seat/airbox mod that u can do on fe450? FYI. I have the muffler that says Husaberg/Kritszman on it. Does that need to be freed up in anyway?
Besides these last questions am I good when I say that I'm gonna go with FMF bomb to either akro/fmf 4.1 rear can and snag the JD Tuner (i cannot find Bazzaz tuner for '10 fe450)

That "trick" is to put in a 390/450 airbox into a 570, so no trick for your bike... The 570 do not have that bell mouth inside of the airbox, just a hole.

The seat-mod is not to recommend either. That is to make a big hole in the seat above the airbox. Good for tarmac but not for dirt.

However I do recommend to make small holes on the top of the shrouds, along the airbox under the seat. I use a soldering iron with a ~3mm point and push through so I get holes all the way. That makes it easier for air to get in and at the same time it's colder air. Normally most of the air is sucked in at the back of the airbox where the fuel hose is connected to the tank. That air goes by the midpipe and is fairly warm. When you make all the holes on the sides you can see the difference on the airfilter, instead of dust at the bottom of it close to that hole you will see dust all along the length of the filter as cold air has been sucked in from the sides.

Thanks man. Appreciate it alot. Last of all, concerns that JD tuner and the Bazzaz tuner. I can't seem to find any Bazzaz products or mymy '10 Fe450 but I found the JD tuner. has anybody used either of these and if they have on a bike like mine what exactly does it do / how does it work? just wondering if its got a whole bunch of different setups in it or if you have to be kinda geeky and know what you're doing in order to program it etc?
