Received headers and exhaust components promptly after ordering from helpful representative. I was very impressed upon inspection of the hardware....super quality and appearance. Installed in one day with no real complications. Sound and performance are exactly what I wanted. Drove 1,300 miles on a trip and determined gas mileage was not improved as I expected it to be. Am told engine may need to be reprogrammed. Definite "thumbs up".
