That got me thinking. Mine do have perforations inside (hard to photograph), the tailpipes are 42cm long and 7.5cm outside diameter. They stay very clean (in the year since I've had the car I have driven around 2,000 miles, I just wipe over the outside after a day's run). They are very quiet, which is sort of counter-intuitive for a Morgan....[Linked Image]
