A replacement muffler which can replace original equipment mufflers with substantially no modifications thereto, and methods for producing the same are disclosed. The replacement muffler is provided with a muffler body which only approximates the body of the original equipment muffler and a pair of replacement muffler nipples secured to the muffler body, having diameters substantially equal to the corresponding nipple diameters of the original equipment muffler and having lengths adapted to produce a nipple-to-nipple length substantially equal to the corresponding length of the original equipment muffler. The replacement muffler may be produced with a six to seven fold increase in production line efficiency by customizing only the nipple portions of the replacement muffler.

The shield is fastened to the muffler by strapping the tabs to opposite ends of the muffler body.
