In an earlier thread, I described how the bolts holding my exhaust box to the rear manifold had fallen off. This resulted in air being sucked into the exhaust system and the production of multiple cracks and bangs on deceleration. It was quite ridiculous but great fun. Anyone with an ounce of sense would have declared that the exhaust was broken - and they would have been correct. I have now 'fixed' the exhaust but I really miss the noise. Somewhere in between 'broken' and 'sensible' is where I would like to be. I am thinking of getting a pair of exhaust donuts (they are only cheap) & drilling a hole in each one to allow some air in. I would glue a metal sleeve into the holes to ensure the donuts don't collapse. I'm also thinking that if I was clever I could devise a way to adjust the amount of air drawn in. Opinions & suggestions gratefully received.
