Okay this is not a technical question just more of a statement thread.  I had a set of Pypes Race Pro mufflers installed on my car yesterday and all I can say is wow.  These mufflers are great.  My old mufflers were Dynomax turbo style chambered.  The Pypes Race Pro's are a turbo style looking muffler but are a straight through design.  Look through one end and see out the other.  The sound is quiet.  Even when openening the throttle they sound great and to top it off I do not have any drone inside the car anymore.  This system is great and could not be any happier.
