I have a FMF pipe on my Zilla and it leaks at the flange on the jug. Driving me crazy, leaking on my new skidplate, plus I need to fix the leak because it should be not leaking. Are those billet flanges with the two o-rings I see on he ebay any good?

  I was thinking about ordering one, maybe another for my 250r which has just started copying the Zilla, go figure.

The billet o-ringed aluminum flanges look really nice and reduce the mess for a short time untill they ware out.  They are also to small to flow well on the high HP engines.  They were originally made for the 250 Hondas.
