Yes.

Please don't assume all FMF exhaust are bad just because they mass produce.

Barker makes a good pipe, but name a bike any FMF pipes works well on??

Dasa is a badass pipe, looks great, but it's just to dam loud.

2002 Honda 400EX
Powerbomb w/ White Brothers E-Series Silencer was the combination to run!

LOL yep i think your right. I miss my old 400EX

He speaks the truth about fmf mega bomb making a good bottom and mid. The problem is there is no top to them. For ride ability in tight trails, it would be good. For lugging and putting its good. I have dyno sheets to show where fmf makes its power, I also have barker dyno runs with the same set up to compare it against.

YFZ450XRacer · 06-12-2012, 08:12 PM

What kind of horsepower numbers can I expect to see with the DASA? Rossier has theirs posted on its an "honest 47". Also i've heard that dasa is around 120 db what is the rossier at?

Buttermilk · 06-12-2012, 08:41 PM

Isn't Chad Weinen running the FMF??? So it's gotta be good right???
;)

skboyce2 · 06-12-2012, 08:44 PM

DASA is a great overall feel, you'll really enjoy the feel of it. My only complaint for it is how super noisy it is on my 501, but then again, I kinda like it that way 0_0

like i said gave it alot more ass, just no top end at all.. which for GNCC is fine.... and i am pretty sure one of the GNCC factory yamaha riders runs the powercore with a megabomb header on his wheeler?

bill_ball-10 · 06-12-2012, 08:56 PM

i would also be intersted to see the fmf dyno sheet if ya have it.

**ctown208** · 06-12-2012, 09:02 PM

i should have kept that set up that i had for my 08, its my take to the hills camping bike/ part time flat tracker quad. i had a mega with the 4.1 that worked awsome in the hills but sucked for flat tracking in my opinion.

topdogjf · 06-13-2012, 12:10 AM

You can think an RTR pipe is crap. Ever hard of any pro rider? obviously not, because rick sponsors dirty foot adventures mx track where pro riders like chad weinen, walker fowler, thomas brown, rastrelli, mark madl, and cam covil ride. Rick helps these guys just doesnt have deep pockets to go out and sponsor riders. Ricks actually got a yfz motor thats super built if anyone is looking for one. His motor has killed and other builders same setup ive come into contact with. The header pipe allows for tuning of the pipe. If you wanna call it crap, your just a hypocrit. He's got dyno results but why would he release his information when its better than what is being made.

buddah · 06-13-2012, 11:31 PM

My builder dynoed a Dasa and Barker back to back on my YFZR and the Barker came off the bottom sooner and made a .25-.50 hp more through the entire range. Both are great pipes but the Barker is extremely loud. I now run a Yoshi RS2 and performs great. Definitely quiter than both pipes.

like you said, for tight woods trails it gives me exactly what i wanted.. i can keep in second gear for most of the trails i ride on and it just grunts through everything
