Eisenmann race sound difference

Hi all,

New guy here. First, I apologize if this has been already asked... If so, if you don't mind, please direct me to the proper thread where this is discussed.

I'm looking at Eisenmann 90mm muffler with center pipes. My question is, what is the sound difference with or without the center pipes for this system?
