Hee hee......that brought back a long forgotten memory for me. I used to ride motorcycles when I still lived in England many moons ago and being a 'bull headed' teenager swapped the 'silencers' on my MC to straight through bells just because they were noisy!
On this particular day I was almost home when a black Lab came tearing out of a front garden and kept pace with me on the walkway, then suddenly shot out between two parked cars directly behind me. I snapped the throttle shut and touched the brakes and waited until I saw his nose about to disappear up the end of the pipe and then pulled in the clutch and end stopped the throttle......lol.
He certainly didn't appreciate 130+ dB plus hot gases full in the face and his yelp could be heard above the din I was making even with a full-face lid on!
Every time that dog saw me after that it would tuck it's tail between it's legs and scoot home as if the devil was after it.....lol.
I didn't keep those pipes on long as I soon discovered it was far better to do 90 MPH and sound like you were doing 30 instead of doing 30 MPH and sounding like you were doing 90!
