I hate to break it to u but just remiving the muffler doesn't do a thing for hp. The only thing it does is make it loud and may actually cause a loss of power unless it's paired with a higher performance cam, valves, ect. A larger pipe may slow down velocity and therefore decrease scavenging in the cylinder. As always with performance it's a balance of many improvements.
I really appreciate this comment, and you are right about needing a good balance of mods. I don't know if you heard at the end, but I was trying to adjust the carburetor to match the new pipe and you could hear the engine have a slight hiccup in the idle. That is due to using a 1.25" pipe instead of a 1" pipe, causing a little bit too much exhuast flow. I have done dozens of 1" pipes paired with upgraded jets and air filter and I can attest that there are significant power gains from those simple modifications. A pipe alone will increase exhaust flow, which would still increase power, but adding it with a modded air filter and bigger carb jets will make 5x the difference. Despite anything, I think we can all agree straight piping a go kart is one of the funnest and cheapest things you can do to it
Which part of the video did you find the most helpful?
Cool projects! The skills you are building now are going to put you leagues ahead of your peers. Keep at it!
Thank you very much!

Ooh super loud!
