Sorry for the newbie question here but I am thinking of getting the Eisenmann Race Exhaust with the oval tips. I notice it does not come with the center section by default and that is another 2500 or so. My question is what does that get you over the stock center pipes? Is the sound (why I really want to do this not really adding HP) changed by not having the center section as well? Also for about 500 bucks less than the Eisenmann without the center section I can get a full RPi GTS that also sounds pretty nice.

So I guess my question is if I am going for the best agressive sound what do I need?

thanks for helping me get my head around it
