About Patriot Exhaust

In August 2000, PerTronix completed the acquisition of Ermie Immerso Enterprises, a 30 year old exhaust products manufacturer. Under the brand names Patriot® Exhaust and Smithy® Mufflers, PerTronix supplies the Street Rod and Muscle Car markets with headers, mufflers, side pipes and do-it-yourself header components primarily through performance warehouse distributors.
