"Remus Racing Rear Muffler" with Large Round Tip.
This muffler is all stainless steel and the size of tail end is 90 mm.
Morimori's wife said, "The exhaust sound is loud !". But I do not think so ! ;-)
However, if I drive very hard, the sound will be SUPER loud ! :-O


Although the material is all stainless steel, why does the rust appear !? ;-)
