Whitman Manufacturing is a fully equipped and fully tooled manufacturing facility with state of the art equipment and manufacturing processes. At Whitman Mfg., we build fixtures, dies and custom machinery on site to produce small engine exhaust components and tubular products (ROPS/OPS). Our in-house, full machine shop-design allows us the luxury of building all of our own tooling. We also provide multiple product lines to specific companies, enabling us to compete on a larger platform. We offer our customers "one stop" shopping with a single vendor. What this means for you is a reduced cost on shipping and back office functions (i.e. accounts payable and vendor maintenance).
The Whitman process eliminates causes for design failure so that customers like you get small engine exhaust components, mufflers and tubular products to fit specific requirements exactly and always on time!

When it comes to emissions regulations, Whitman is ahead of the times! Read More...
Not only does Whitman Mfg. produce some of the quietest mufflers in the industry, but we also ensure that our products meet emission requirements for an eco-friendly environment. By establishing optimal emission solutions on a day-to-day basis, Whitman Mfg. has led the way in North America, as we rigorously follow regulation requirements and adhere to emission standards. Our approved emission-compliant systems are designed to meet the acoustical, thermal and engine performance objectives of our customers.
In fact, our team of experts have been working with leading engine corporations and OEMs to uncover efficient solutions to reduce NOx, HC and CO emissions, as new California laws and EPA emission regulations demand a considerable decrease for a cleaner environment.
In order to meet EPA Tier 4 regulations, in 2012 all off-highway engines will require after-treatment, and in 2010, CARB will be implementing fleet requirements, which will call for modifications with existing equipment, involving Diesel Particulate Filters.
Nonetheless, at Whitman Mfg., Diesel Particulate Filters and Diesel Oxidization Catalysts have already been set in motion, and are being incorporated into our exhaust systems. Also, solutions for the after-treatment of NOx emissions are being significantly developed with the best available technologies and individuals who have been working in the industry for over 15 years. Our employees are highly qualified in the development cycle, stretching from design to production, and are dedicated to ensuring customer satisfaction in a timely manner.
