Based in Salinas, California, the company also produces aftermarket muffler kits solely for Harley-Davidson. Tenneco Automotive has reached a long-term supply agreement with Harley-Davidson to continue these relationships.

"This acquisition is the first in our company's five-year history and represents another execution of our consistent strategy to grow through niche opportunities.

Tenneco Automotive will lease the facility in Salinas and will assume the current leasing agreements at the other Gabilan facilities.

The business has about 240 employees, the majority of which are located at Gabilan's headquarters and main manufacturing facility in Salinas.
