Does exhaust affect engine performance? (self.motorcycles)

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!

most of the back pressure that effects performance comes from the cat, not the pipe. Expect minimal horsepower from a bolt-on. A cat delete would make a difference, but would also cause your bike to fail inspection (depending where you live)
