Fci vs Cfm

[kfx450r08]

Hi ive seen other threads on this but nothing real clear it seems that the power gains from fci intake/box are close to cfm intake/box i mostly trail. ride And i would like to know which one will have the most gains with exhaust and programmer. Also whats the advantage of full exhaust over slip-on the headpipe is the same size for most unless its a step header plus i like the heat shields on stock pipe. Am i going to lose that much power with just a slip-on. Thanks

I had the cfm it's okay good increase in power but the fci is by far the best intake out!get the box with it if you in wet conditions!and doing the big three a full exhaust is the way to go along with a pc3 or pc5

Get the FCI you won't be disapointed.

i agree right now i think the fci is the best on the market.

Yes the FCI is great but keep in mind if you are going with the box there is a small problem the filter fits so tight it wears a hole in te outerwear I talked with FCI and they are suppose to have a little shorter filter ready in the next week or 2 that will solve this problem but just want ed to let you know it might be worth waiting a couple weeks to buy until they get teh shorter filter so you dont have to worry about the problem.

FCI with the box!!!!!

i wouldnt **** up the engine going through mud?

No i ride mine in muddy conditions. I just drilled 2 small holes in the box to drain any water that gets in. Have had no issues with mud getting in. But to be safe whenever you stop pop the seat off and take a gander in the box.
