Will Yoshi & FMF exhaust parts work together?

[BRAD]

Hey guys will the FMF Hi-Flow header work with my Yoshi Rs-7 slip on muffler?

Thanks,
Brad

I doubt it brad

I bet it will. both companys make slipons to fit the stock header, so to make their header work with their slip on it must be in the same place as the stock header......if you follow.....lol.

You should be fine. I do know that guys are doing it all the time in the predator world.

The only way it wouldnt work is if the state that you have to buy the full exhaust, thus telling you that their headers are different.


This is meirly a edjumacated guesss though, only way to tell is to try it.

I'm with preddy on this, I bet it works just fine.

I think it will work....I had same question about putting FMF powerbomb header on mine with HMF slipon, will fit.

Thanks guys.  I think I may try it. Worst case if it dont work I will return it and get my money back.

Header is only worth a 3-4 hp so don't spend too much

[BRAD]

Yeah true. I may just say screw the header and get a piston and cam

If you add internals, the stock header will become even more of a restriction.  Then the aftermarket header will be worth more than 3-4 hp.
