John has the right Idea!   We could put such huge expansion chambers  on our 
exhaust systems, that we should get a 20%+or better increase in power, and 
sound no more obnoxious than the standard Chevy 3.1L corsica engine.  Thus 
more mundane applications, minivans(Bimbo Boxes, referring to the driver as 
an airhead regardless of gender), Volvos(no offense TeriAnn) could be use 
smaller more efficient engines to produce the same amount of power.  Of 
course the LBC set would use it for a straight 20%+ power gain!  The only 
question I have is, doesn't the car pollute More?  I know that Honda had 
emissions problems with its variable valve timing engine.  Apparently, when 
the engine used very high gas to air mixture, the SO2 and CO 
concentratitions were higher.  This contradicts logic to some degree.  Does 
anyone know why that is the case?
