Exhaust question type r

Twincam.22

Got a ninja II exhaust for the type r and wasn't it a 2.5" one never checked me own and it was a 3" !!!!!

Anyway comparing both see little fins inside my own and it looks pretty narrow down at that section too...anyone know would removing it make nicer sound? I bought the other one cause it's little bit louder my own is very silent. Not sure of the brand but there's two places where tags are off. The tip also has a section tacked in makes a more gradual change in section out to the tip end might take that out too....

Never seen that before...must create some sort of a vortex to get the gases out ouicker or something
 
Hard to know I be half thinking it tries to guide the gases through the muffler section more so rather than straight out which would make it quieter I'd say....

Half thinking of welding the new box onto old pupe
 
Knock it out It's only for making a whisle noise I'd say got nothing to do with flow or back pressure
