I got the exhaust with the bike when I bought it, sadly it doesn't have any papers and there is no brand written on the exhaust so I have no idea which exhaust it is.

That definitely looks and sounds like the FMF Q4, most popular exhaust for these. That popping means it needs fuel added to account for the exhaust. Bigger jets if its a carb model or fuel tuner/02 delete if the EFI model.
