ive got a turboed bike that has very little space to work with. Its not emissions testing that im worried about, its just a bit louder than i prefer. unless i change my entire design, ive got space for about 6" of resonator in there. think this will make any real difference? i cant imagine the sound level being too much different than a turboed car with a 6" resonator.

 

i was just reading some pages online and found that my "resonator" terminology was wrong. resonator (Helmholtz Resonators) being different from a glass packed exhaust, my title should have read, "will a 6" glass packed exhaust do anything?" but my question still stands 6 inches...?
