Racing Beat Muffler Dimensions?
 

Hey guys I've had about enough of my cannon muffler so I'm thinking of getting it cut off and a new muffler with a larger baffle area put in.

Its currently a 3 inch cat back so does anyone have a rough dimension of the racing beat muffler (not the tip) so I can tell the exhaust shop roughly how big I want it?

I'm just sick of the drone of the car and having to crank up the stereo to drown it out. Also I usually start the car and warm her up in my garage so everytime I do this it echo's and wakes up the neighbourhood especially early in the morning or late at night.
