I just got back from the Rallye Baie des Chaleurs. I got 3 or 4 dude who asked me "What is you exaust ? sound good" so I told them "4 washer each side"... they were like . So I explained that I've only putted two washed on each bolt to create a leak, that mod is called "Hog Zawst" and they told me "well, I'm pretty amazed, sound very good ! :eek:"
