Ever since I finished my 280ce a couple months ago I've been trying to get the exhaust note in the right range. I don't want a stock exhaust but I want something with a sport sound to it. I've tried a couple different muffler set ups and it's still too loud. My latest attempt is going to be a catalytic converter that will be added. Has anyone changed there stock mufflers for something else and if so what did you use? Also how loud is it compared to the stocker? Thanks
