Exhaust! FMF powercore 4 or factory 4.1?

I have a complety stock 2009 crf 250x. I want some suggestions on what exhaust to get. I am currently deciding between the fmf 4 and 4.1. I am looking for performance but also like it louder. Which one is better for a stock bike? Which one is louder? Any other brands reccommended?

 So it's not worth the extra $$$ for the 4.1?

honestly no

Why do you want the loudest pipe?

I was curious which was louder but I decided not i don't want it because I would like to ride on public trails and don't want to annoy anybody

The 4 is quieter than the 4.1 but the 4.1 performs better than the 4. They are different exhausts and each have their place, seeing you have very little to gain from an exhaust, I suggest the 4
