Does exhaust affect engine performance? (lemmy.world)

I have a 2021 rebel 500 and thinking of getting a radiant cycles shorty, but according to my google search, exhaust not only muffles the noise, but also improves engine performance.

so my question is, if i change my stock exhaust to radiant cycle shorty, will it affect my engine performance? Does it hurt my engine? thanks!

Generally exhaust has a smaller impact than other places in the power train, but it definitely has an impact and moreso in a motorcycle vs. a car.

Generally, freer flowing exhaust will make more horse power however if you go too crazy (think open headers) it can decrease low end torque.

For a motorcycle I say go for whatever exhaust you want and you'll be fine. Motorcycles are high reving small motors that could use the extra air flow from the exhaust

Appreciate the input. I just want to fresh things up a bit by change the exhaust and how my bike sounds, was afraid the new exhaust might do the engine some harms, hence the question.

It can actually do your engine harm if not done properly. There are cases of exhaust valves clearance changing drastically because of aftermarket exhaust. If you're not going to remap the engine then don't get an exhaust.
