Newbie here with a 2009 4S and Akrapovic exhaust question. Is the Akrapovic cat-back exhaust system worth it over the Fabspeed and Tubi systems? Nearly half the cost but at the end of the day, I want the best HP/flow gain along with the best sound with no drone. I am comparing the complete system replacing all three mufflers. The stock headers/cats will remain Thanks for the help.

 

On a .2 car you want to ditch the center muffler for a bypass with any system you go with so only consider systems that don't have a center muffler at all.
