Does anybody have any info on the power core iv complete system. My dealer told me about 8hp increase. what do ya'll think?

 

I have heard from many people that the Powercore IV silencers fall apart very quickly and FMF will not replace them or give you a refund.

 

yeah,

I heard that as well...I personally have the powerbomb headpipe and a Pro-Circuit t4 silencer...lots of torque, not a bad combo. I don't like the design of the power core silencer after seeing one first hand. A few people say bad things about the Big Gun, but I think I would use that system if I had it to do over again.

 

Will the powerbomb or bigGun head pipes bolt up to the WB e series?

 

yam660r,
I have the Power core 4sq, slip on. I think the difference is minimal. Better throttle response for sure, feels as if mid picked up some too. The only reason I bought it was because FMF had it available early, as it relates to when the Raptor became available. I've had my Raptor since mid Sept.
Now, there are much better exhausts available. TC, CT, Trinity is working on one, Powroll, etc. None of these were the first, now just MUCH better. So now that there are companies that have had more extensive testing, you can find quality exhausts that are making huge power increases. FMF is small in comparison.

If I were you, since you are just getting to the point of purchase. Call around, see what other products these particular companies are testing and or making.
Hope this helps, good luck.
