I have a cat back Edelbrock exhaust system on my car it isn't too loud at all, it has a nice purr but I also hollowed out my catalytic converter to get it louder and added edelbrocks headers also. you can put the cat back system on now, then later put on Edelbrock headers, the headers come with a new Y-pipe that goes down to the converter. the only thing with the Edelbrock cat back system is that the tail pipes don't really have that great of a look to them.
