I am making a custom cat back exhaust, 2 1/2 inches. It will start right after the cat converter, i am getting rid of the first small muffler. It is not a profesional cat back, but will it get any gains besides making the car louder? I can live with just a sound difference, but any performance will be cool. :smile:

You Should Get A Small Perfromance Boost Out Of It But Not Much
