Since we pushed back the engine, we thought we might have to custom make headers. After trying countless header combinations, we found the Doug’s headers fit realty well. The only problem was that we didn’t get the headers that were coated and forgot to treat the headers after fitment. After the testing at the track we removed the exhaust and took it over to Embee Coating in Santa Ana, California, where Jeff Conrad helped us get the headers and exhaust back on track. Rob selected a gray coating for the complete exhaust system.
