Fmf sent me a dynochart of a stock Raptor and one with their slip-on muffler.

Hey shollz, thanks for the info. What muffler did you get?

 

Great work Shollz! Looks like FMF has a solid design with good gains. I'll bet the torque graph is even more impressive. One thing that catches my eye is the rpm's going slightly past 9000 rpm's + still making about 23hp at 9000 with the stock set-up.

 

What is with your website address? I cannot access it.

 

Hey I just ordered the FMF pipe on Monday it should be here Friday. I'd love to see the dyno chart but I can't seem to get in to your sight. Any tips. Thanks later

What are they claiming it looks like 3-4HP Peak gain. If WB is 5HP Id have to go wtih theirs.

 

DS650, Banshee, 400EX dyno charts here: www.quadstore.com/sys-tmpl/dynoruns/

 

Not to start a flame war, but here is a banshee dyno run with stock and aftermarket pipes, total mods cost was $800 and shows over 35 HP available from about 7 to 10 thousand rpms.
