WR250R Exhaust and EXUP valve removal

Walking through the removal of my WR250R Exhaust and Exup Valve parts in preperation for installing the FMF Q4 and Megabomb header, and PCV

Thanks.
Got a Yoshimura RS-4 Exhaust in the post already.
Didn't know I would need an EXUP eliminator. Just ordered one now.

Do you know what that bracket is called that hold the side plate that screws on to the sub frame is called? The one by the warning decal? Mine is missing and wanted to buy one. Please let me know. If you know thanks.

I have a 2017 WR250R......ordered the FMF Q4 exhaust, AIS block off and the exhaust servo eliminator....they have all been delivered with the exception of the, exhaust servo eliminator. I have the EJK fuel controller already installed on my bike and the air box flapper mod done to it. Do you happen to know if I can install the Q4 and AIS on the bike without the exhaust servo eliminator?

MrDirtdart hey man I’m about to install all the mods you just listed. How were your results?

[@troyg.katucki4436]

What does this do performance wise to the bike? Can you leave the stock exhaust on after doing this?

[@travrsx]

Dark Torch no point to do this mod if you’re keeping the stock exhaust. If you remove the exup, on a stock exhaust, you may gain a small amount of top end power, but will lose some low end grunt.

[@MotoStrikerUnit7]
