I've heard great things about both the Termignoni exhaust System and the Fast By Ferracci exhaust system. I know that FBF does not manufacture their own exhaust and that they went with FORZA before. So, for use of the message board it will be called the "Fast By Ferracci exhaust system/kit" or the "FBF Kit". I want to get your opinion. Which one is better? And why do you think so?
