For the posts that have been added to about the bikini models endorsing mufflers: http://justacarguy.blogspot.com/search/label/Mufflers and http://justacarguy.blogspot.com/search/label/rated%20R

Doug Thorley mufflers, the Muffettes and The Super Muff QT (who would be interested without the double entendre and bikini model?)
