Hi, The 1927 Flying Squirrel had TWO exhaust pipes, one on each side, and the coffeepot was empty, giving a noisy but fruity genuine Yowl. The factory offered auxiliary silencers but these were not full size Howarth but a shorter version just for this application. Our Registrar John Underhill has a drawing available for you to make a system, and Tim Sharp can supply Howarth silencers that can be shortened to the cut down version. Regards. Brian
