does anyone have the fmf 4.1

[outlaw450mxr]

system on their 525's or 450's? if anyone does, how do you guys like it. im thinking about going with the 4.1 slip on and the mega bomb header. i was thinking about getting a yosh, but they only show a 1.5 horsepower gain, so i dont think 1.5hp is worth $800. does anyone know how much the 4.1 gives? o and pictures of the 4.1 or megabomb on an outlaw would be great too.

thanks.

i contaced fmf and they dont offer any dyno numbers and i haven,t heard anything good about them,hmf only has a slip on and claims they couldn't get better numbers w/ a header. yosh claims 1.5 but i think thats without jetting. there tech couldn't give me any info. www.ctracing.com shows the best results and include main jets only they claim 10-12 hp and have dyno # to prove it. . alba ,and ac racing also have exhaust. good luck finding pics on any though . i have exstensivly researched exhaust for our 450's i ordered th ct and should have it this week so i will post pics when i get it on ...... hope this helps

thanks bro, but i found the fmf complete system for $540 and i called fmf and he told me it would give 6-10. and ive seen videos of the 450 with it on, it sound really nice, so i ordered it, should have it in a week too.

I have the 4.1 slip on and it's a difference maker just having the slip. Here is a pic.

Did you find the FMF for 540 online somewhere or just from some local shop?

Hey outlaw450mxr
I take it you have a 450. I have a 525 but want to get the4.1 with a mega bomb. Have you got yours yet? and if so how is it? Aso where did you get it for $540?

[outlaw450mxr]

yea i got it like a week ago, its amazing, sounds really good too. I got it from a website, its either starcycle.com or starcycles.com cant remember right now which one, but i dont have the megabomb i have to powerbomb header,the megabomb is 500 but it should be worth it.
