I am thinking of purchasing a FMF Q and powerbomb header for my 04 wr450. Anyone out ther have the same set up? Any comments, good or bad? :)

My understanding of the powerbomb is that you gain bottom end but due to the smaller header diameter you get reduced power up top. I rode a WR250 with this set up and liked it over a stock WR250 pipe. FMF Q seems to be very popular on the WR bikes. :)

i dont know i am just looking for an exhaust system to give a good overall power gain and still meet sound requirements in California. :)

I have a powerbomb and didnt notice any topend loss. Mine is the same diameter as stock. I have heard that there are two different types standard (same size pipe in front and behind the bulge)and tapered (smaller pipe in front of the powerbomb bulge). I have not seen or ridden the tapered but i am happy with the one I have. It is a good Idea to get the stainless and not the ti, much more durable with minimal weight gain.

I just installed a Q on my 03 WR450. In looking for Q info on TT, I came across a post that mentioned the rangers in California stating that approximately 90% of the Q's on WR's are passing the 96db law in California. I rode mine for the first time yesterday and it was noticeably quieter than the stocker. :)
