Auxiliary Power Units

Approximately 60% of our sales draw from the production of our custom designed mufflers and exhaust components for not only on-road trucks, but also for the OE manufacture of small engine related equipment—turf care, APU and generators. New laws in California have set the standard by requiring Auxiliary Power Units (APU's) to meet level 3 emission standards, which requires the installation of Diesel Particulate Filters (DPF). Whitman manufactures mufflers, manifolds and tailpipe extensions for APU's.
