pooolice pulled us over for noise
sounded real sweet and he also said that with the tweaking of a screw he can just turn the sound completely around.
I wonder if they still make those
mine was a simple (store bought)
round piece about the size of a quarter with just a few holes in it
so the quarter size thing had a small piece smaller than pencil size
maybe an inch long attached to the quarter size flat baffle
I drilled a hole just in from the end of straight pipe
slid the end piece from the inside of pipe and through to ourside
had a little knob that screwed onto the small round piece sticking through
twist of a finger while riding -- on or off as wanted
true story -- sad for my buddy -- but true
we were riding our motor bikes and the pooolice pulled us over
before I even came to a stop I turned the little wonder knob
the pooolice said that one of our bikes was very loud
a Honda 90 with a straight pipe is a trip to hear
the poolice had each of us start up and rev our bikes
my buddy got a ticket for excessive noise
he was cool and didn't tell the pooolice the truth
it was me with my knob THING
I owed him a big one for taking that ticket
as we ride those things
