Because the sound echos in the larger area before it leaves the exhaust completely. Think of it has talking into a bull horn or a road cone.
I wish someone made a 4.5" bolt on tip about 12" long. Personally the 5" tip is too big, for me atleast. Heck I would even like to see a 4" tip(factory size) that is 12" long.
Pretty well sure Gibson makes them. Not sure but I think they’re bolt on. That’s the ones I’m looking at
