This is exactly what a "how to" should be! EXCELLENT ! After 6 months of waiting finally got an Q4 pipe...Can't wait to get started on this !!! THANKS GUYS!! Definitely will make the job easier !!!!

[patw]

Thanks guys. I was actually trying to reinstall the whole thing back to stock (exhaust was way too loud) and this was easily the best video I'd watched on it. Between this video and the manual it was very easy. Thanks!

[DanSopher-qf]

Very good video. Great detail. Thank you. I'm mod'ing this weekend with a yoshi, ejk, exup-elim. Great idea on the foam at the flapper.

[jpyoung]

Great video my man. I've been looking for this for a while. Snatched up a 2020 wr last year. Will be doing everything you showed on here. Keep it up.

[carolinacopperhead]

Thank you for an excellent demonstration and how to do this job. I watched several how to videos before I started, but yours was the best that I found. I chose to go with the Yoshimura slip on Exhaust and the Dyno Jet Power Commander 6 fuel controller.
Your demonstration showed me that I could do this modification. Keep up the good work.
Thanks

[MotoMeeple]

Great vid, especially the close ups. I managed to score a new FMF plus the megabomb off eBay. Did all these mods in about 3hrs, and it makes a great bike even better. Only pain was uncabling the exup. Left flapper stock

[shepdualsport]

Great Vid! Best explanation of mods install I have seen yet. Kudos!

[trevorwarren]

Perfect video. Step by step was easy to follow. Doing all this plus the powerbomb header on my 2015 WR250R

[darylhill]

Yeah, I did the same stuff on my 2011 X I still love the bike bought it new

[Jm_Cosmetics]

Hi. Again, where did you get you emulator? My Yamaha is 2020 WR250R I been looking places no one please.

[darrellhay]

I have that same exhaust and a tuner on one of my WRs. I agree completely, smoother and more responsive power delivery, and louder. Additional power? Meh...maybe, but whatever, it has enough anyway for the dirt. The brap is great, but original stock quiet is nice also. Oh hey we went to Tahuya finally a few days ago and didn't really enjoy it for all the round rock and gravel everywhere (plus cranky from all the heat). Funny enough had a bike break there also---fuse blew and would not allow the starter to turn. Fortunately we didn't have to tow it back LOL. Much prefer Capitol Forest for dirt riding over SlickRock-huya.

[MarylandWearAndCarry]

Great video, as always! Is he still using the same settings on the EJK? Thanks

[mototurtles]

Thank you so much for sharing! I am looking to buy the exhaust but can't find one. Where did you get yours? As well, do you have any suggestions about what to start with? EJK unit or FMF first?

[potaylo]

Was there a gasket on the stock pipe?..I did not see one in the video. I am atempting to go back to stock.
I am a bit concerned without the AIS I will have introduced backfire popping to the stock muffler> Of note, there was a treaded clip on the FMF when I took it apart. I would think that would be suppied as the FMF muffler did not have a threaded connection. your aftermarket muffler sounds not as loud as the one Im replacing. I would leave the one Im trying to replace if it sounded like yours.

[Jm_Cosmetics]

Hi! Thank you for the video and information. I did just replace my exhaust for a FMF I finished but now my engine light is on. What could be please need help. Thanks. I don’t have the emulation I need to buy it.

[kristopherr]

The flapper mod isn't done properly. He blocked off the airflow created by removing the valve and taping down the door. It doesn't sound like he plugged it with the foam just for the video since he said he keeps the foam in there to keep out dirt...he'll succeed in keeping out air and choking it off, also.

[kuladeeluxe]

I had my bike with ejk controller on a dyno and the tuner was unable to get it lean at Max throttle under max load. Works well otherwise. He said the dynojet power commando has a lot more control.

[gcoop]

Great video! A question: What size was the replacement bolt you had to purchase from the hardware store? My fmf pipe arrives in 2 weeks so I'm getting prepared. Cheers!

[lomparti]

I just bought a wr250x. Previous owner(s) already did all these mods to it. I was wondering what the block off plate was for by the exhaust port lol. They also did the mechanical cam chain tensioner mod and also added a speedohealer.

[MrJonnywisecc]

I also have a WR250R. Have you had the bike dynoed after all of that was done to it? I just bought new rims, sprockets, and a chain for mine.
