standard exhaust performance

[squeak]

I am lucky to have a 7/8" pipe bender and made this tailpipe out of a steel tent pole. There was some discussion on the old forum at the time and a contributor who had flowtested a 7 engine was of the opinion that size was OK.  My wife had been complaining  the at the time that a side exiting exhaust was too noisy and smelly.  Quieter and no change in performance, standard maggy engine with a 1" SU.  cheers  Russell
