FMF Q4 and stock header? Fitment issue.

Hi everyone,

I just picked up a Q4 silencer for my 2015 WR and was told it would work with my stock header. This doesn't seem to be the case, as the Q4's tubing is much thicker than the stock header. How did others get this combo to work?


Any help is greatly appreciated!

Theres a alum spacer/adapter that goes inside the q4's pipe so it fits on the stock head pipe, im not sure where you bought your q4 but mine came with the spacer.

^^^ yep what he said...i just put my Q4 on as well, and used the adapter. No problem

need to take out the old the little spacer thats in the end of you stock header. I used a big flat head and hammer to tap it out.. should fit peachie after that.
