In just a short amount of time they all will be having exhaust. Some top performers on other 450's are DASA, HMF, Yoshi, ESR, NMotion, Rossier and I'm sure Pro Circuit will be good. Stay tuned here for dyno numbers from FUELATV.

ESR make a great product; we have raced with ESR exhausts for the last 2.5 years and have not had a reliability problem, and they make awesome power.

ESR is a very nice product and I believe that they give you an option for the head pipe, MX or GNCC.

No dynos yet. I am not going to put an ESR on my bike. I am trying to be patient. I have talked with motoworks, they are about 2 weeks out. That may be my choice, but we will see.

i seen that fmf has a full exhaust with power bomb header! :banana: but im still unsure whos exhaust ill use. im keeping my eye on dmc since there exhaust has really boosted the 700 raptor torque and horsepower right at 50hp/trq

Those are nice numbers on the Raptor for just the 3 upgrades.

so just cruious cuz i am kinda new to the aftermarket parts field j/w if lets say a full Dasa system would be improved or could be improved with the swaping of their header with a FMF Megabomb? and if so would it be worth the extra cash for the megabomb and does Dasa have a slip on?

any help would be greatly appriciated

Thanks

If you like a FMF get one they will all be close in peak just the powerband will be different. DASA uses a stepped header and from dyno numbers I've seen produces more power than FMF. DASA only has full systems.
