FMF silencer issues...

I just installed a FMF Q series pipe on my 99 YZ400 and I have noticed a few things and was wondering if anyone else has seen the same problems.

First off, I can't use the circular gasket between the header and silencer because the clearance is too tight. Tried teflon tape and hi temp RTV, both of them blew out, duh..

When I was washing my bike today, I noticed the silencer has a dent in it from my brake caliper when I bottomed the suspension. What the #$!@#$? I thought they would do some research on the fittment of this pipe before selling it to the public. I'm pissed...


Pat, Try chamber seal, its meant for exhaust headers. I used this for my 2-stroke where they all leak oil at the jug, with this it did not leak one drop of oil. You can buy it at the motorcycle shops around $6.00 - $7.00.
