Performance Exhaust - C230 Sport Sedan
 

All,
I have a 2004, C230 Sport Sedan with the four cylinder supercharged motor and a six-speed transmission. I have been searching for more power. 182 horsepower just doesn't cut it. I have been looking for either a cat-back exhaust or headers, hi-flow catalyst, and performance exhaust. So far, it appears Kleeman offers a header with an integral 200 CPI catalyst. There are many performance exhaust manufacturers like Supersprint, Remus, Eisenmann, Billy Boat, and Kleeman. However, I have not found any reports on which are best. Everyone seems to offer stainless steel and everyone claims light weight and more power, but how much and how loud is it? I like a satisfying growl which can howl when you are on the gas, but droning at constant speed is definitely out of the question. So, anyone have any experience here?
