by perforated mufflers(i.m sorry if thats the wrong term) i mean,that the inner tube of the muffler has holes in it at to absorb the sound.well even i thought so that the sound is characteristic to the state of tune and displacement.but i saw a zen with the same sound with just exhaust muflers.well i have stock headers,the first muffler has replaced the catcon,and the 2nd muffler has replaced the stock muffler.the exhaust pipes are stock and overall diameter was not increased as it wud have led to loss in low n mid range grunt.I got the mufflers installed from Performance auto,noida and the the mufflers are branded as Remus.wen u hear a superbike u hear somethin like a turbine spinning or something....the best way to explain is just relate it to the sound of a superbike and ul get the picture.i wud go to autopsyche but he is just too far away(gurgaon).and i'm talkin about my zen.
