Doug Thorley Headers Performance Catalogs
As we near our 50th anniversary, our executive staff is extremely proud to announce that Doug Thorley Headers has amassed our greatest team ever. From our R & D department, engineering staff, marketing, sales staff, to our production team and shipping department. In the last year, our customer base has grown by leaps and bounds. While we remain world famous for the invention of the Tri-Y Header and ease of installation, we have continued to expand our product line to include the latest models. In addition, we are introducing our new line of HDX –series of headers. These headers are super heavy duty and specifically designed for those who have motor homes, trucks and off road vehicles that are susceptible to extreme conditions. Also, we now produce and sell the finest Sanrail header-exhaust that's available anywhere. We are still a 100% American made product, which is produced at our factory in Corona, California. Our goal, as ever, is the maximizing of torque and horsepower gains and we will continue this time honored tradition as we move into the future. All of us at Doug Thorley Headers thank all of our customers for your continued support over the years and for recognizing that our headers and exhaust systems, dollar for dollar, are the very best value in the industry. Doug Thorley Headers was on three Speed Channel programs in 2006. We were on 2 (two) segments of Cut, Chop and Rebuild, and one segment of Street Tuners. They returned on May 30th,2007 to shoot another special program. Speed Channel is especially impressed with our ease of fitment and the time it saves during installation. Our staff of 130 people has a long history of working at our company. We must be doing something right!!!
