Toomey with fmf?

[BlairGreen]

I have an fmf slip on but would it be possible to run a toomey header with the power core 2 silencer

Well any two stroke pipe is a certain specific length to aid in performance. A toomey is mostly for top end, and and an fmf is mostly for low/mid. So they are different lengths. However, this "length" only applies to the geometry of the header, after the expansion chamber, it doesn't matter how long it is. So I would say you're fine with putting the powercore 2 on, provided it all fits on and bolts in place.

I am unsure if the two are physically compatible but the slip on is a full flow, straight through design which should not create any unwanted back pressure.

The Toomey SST muffler may not be compatible though, they are usually sold as a matching system.

I have a toomy silencer. P.m me if interested.
