About Our Company

Galles Filter & Exhaust is a small Montana company where customer service is a priority.
My name is Todd Gainan, managing owner of the company. The Galles Family started our company in 1952 and ran until retirement in 2012. We are committed to maintaining the high quality products and service the company has come to be known for.

We specialize in industrial, commercial, agricultural, and auto filters as well as heavy duty exhaust, intake systems and more. We service Montana, North Dakota, South Dakota, and Wyoming. We carry the widest selection in our four-state area. Our large inventory allows us to offer same day shipping on most orders. You can depend on us to provide you with the products you need promptly, and at a fair price. We have experienced employees that understand the filter, intake and exhaust business very well. In fact, we will proudly help you find a solution to a problem whether you buy the solution from us or not.
