Stanley Muffler Co, Inc. is a manufacturer of aluminized tractor mufflers and industrial exhaust systems. Stanley Muffler specializes in OEM replacement mufflers and exhaust products for domestic and foreign agricultural tractors. Each Stanley muffler meets or exceeds the noise decibel level and back pressure performance requirements of the OEM part. Stanley Muffler customers know they are buying a specially designed part for their machine, not a universal fit muffler. Stanley guarantees that each part is manufactured for form, fit, and function. Every Stanley Muffler fits the machine it was intended for without modification. All design considerations, including weight and color, are carefully researched during Stanley’s product development phase to ensure long product life and customer satisfaction.

Stanley Muffler presently manufactures OEM replacement parts for well-known brands such as Case, New Holland, Ford, John Deere, International Harvester, Massey Ferguson and many other brands.

In addition to our proprietary product line of mufflers and exhaust parts, Stanley Muffler manufactures custom exhaust systems for engine powered light towers, auxillary power units, and other industrial applications.
