340 muffler decision

Perhaps we could start a "muffler of the month club".. Devise a common size and a method of attachment, with perhaps sliding band clamps so that you can swap mufflers in about 15 minutes. Get 6 sets of mufflers in the rotation and rotated every 30/60 days.. That way instead of piling up 3-4 sets of mufflers in the corner of the garage everyone could see/test what they might like.. That way you can change the sound of your car without piling up mountains of old mufflers at $200+ per set.
