Hey I've had a idea running through my head ever since mac came out with the pro-chamber. Im wanting to fabricate a dual in dual out single chamber muffler where mac just put the box in their mid pipe. Any ideas on how this might sound? Im wanting the aggressive sound from the pro-chamber but don't want the flow reduction of the pro-chamber after i go long-tubes supercharged . I was thinking of a flowmaster single chamber, magnaflow single chamber, or a cherry bomb single chamber. drone isn't really something I worry about so any ideas to toss around?
