Thanks for the comparison between the two, that really helped. I'm leaning towards the Powercore given it's louder - I want to be heard before I'm seen for precautionary measures.
I can understand that reasoning. Just keep in mind, it is VERY loud. The audio in the video doesn't really do it justice. It's louder than my Yamaha WR250F with a full FMF system. I just wanted to give you one more comparison in case you've heard a bike like that in person.
It probably does restrict flow. If we wanted to squeeze some more power out of it, we could run a full system with a larger header, but the muffler accomplished what we needed. A little more responsiveness and power and lower temps on the muffler.
We made a quick video of these foot pegs: ruclips.net/video/PAq3GMO2CM8/видео.html They are from Amazon: www.amazon.com/gp/product/B0BRFPYWP9/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&th=1 They aren't the greatest to be honest, but for the money they get you a bigger platform on a budget. As I explain in the video linked above, they cramp the space between the controls and the foot pegs. For my son with a size 10 boot, it works alright, for myself with a size 13, it's way too cramped between the foot peg and shifter lever. We have had some of the teeth/cleats come loose, but they haven't fallen out.
I doubt it affected top speed very much, but it was definitely an improvement in power. The bike revs more freely and the throttle response is better with the Q4. Top speed would be more a factor of final gearing, but the Q4 would definitely help you reach top speed a little quicker.
We did notice that if we chop the throttle from wide open to nothing, it will backfire. Other than that, it runs great. As far as being lean, I plan on pulling the plug and diagnosing it. I'll post some video when I do, so stay tuned!
@LagBros_3 I had a 2021 klx300r. At the time, no aftermarket exhaust was available, c0vid era. So, I had to make a complete system for my bike. I first tried removing the stock baffle like you did. But it didn't do much. The pipe I made made a big difference, though. But what really helps that bike us the Dobeck fuel tuner and opening up the airbox. I think I did the pare valve delete kit as well. Also, replacing the o-ring chain with a high quality non o-ring frees up some power. Those bikes are a lot better than they get credit for. The mods I did made it even that much better. It is tall, though. But it's hard to beat for tight trails. Especially for the price.
@Gigachadly If I remember correctly, right under the seat, you'll see a snorkel and cover. They both should pull out. We work on a lot of bikes, so it's hard to remember exactly. If I'm wrong, yes, you can drill 4 or 5 one inch holes in the top of the airbox. But I would recommend getting the fuel tuner before you do it. Letting that much air in without adding more fuel will lean out the mixture and cause it to run hot. If you are interested in a full system for one of your bikes, let me know. I took the system that I made off before I sold the bike. It's trail ready with a built-in spark arrestor.
That must have been quite a bit of work to build a full system! Sounds like a cool project. I agree, these bikes don't get enough credit at their price point. And yes, there is a snorkel that can be removed, and I'll have to do some research on the pare valve delete. Before I do any of that, I am going to get a tuner as you mentioned. In my opinion, these bikes already seem to run hot so I don't want to make that any worse.

great video . but doesnt that small headpipe restrict alot of flow ? I had a stroker pipe and the head pipe was much fatter.
It probably does restrict flow. If we wanted to squeeze some more power out of it, we could run a full system with a larger header, but the muffler accomplished what we needed. A little more responsiveness and power and lower temps on the muffler.
Awesome video!
Thanks!
Does the power core have the spark arrestor installed in this video?
Thanks for asking... and no, we did not install the spark arrestor when we tested the muffler. I forgot to mention that!
what foot pegs are they
We made a quick video of these foot pegs: ruclips.net/video/PAq3GMO2CM8/видео.html
They are from Amazon: www.amazon.com/gp/product/B0BRFPYWP9/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&th=1

Very nice video. Thanks.
After install FMF Q4 Could it help top speed better than the stock exhaust?
I doubt it affected top speed very much, but it was definitely an improvement in power. The bike revs more freely and the throttle response is better with the Q4. Top speed would be more a factor of final gearing, but the Q4 would definitely help you reach top speed a little quicker.
Thank you very much👍👍
Does the new exhaust make the bike run lean or backfire?
We did notice that if we chop the throttle from wide open to nothing, it will backfire. Other than that, it runs great. As far as being lean, I plan on pulling the plug and diagnosing it. I'll post some video when I do, so stay tuned!

@@bmotomo421how did you open up the air box?? Just drill holes or something or?
