Check out this recent Doug Thorley Headers customer review: Robert Y from Monument, CO says "I've had my Thorley Headers installed on my '89 Toyota Pickup for about a week now, and they are fantastic! The sound they make is truly melodious coupled with the FlowMax muffler. It took about five hours to get them on, but well worth the effort. Fitment is perfect. Not only has it increased my MPGs from 18 to 22, I can feel a definite boost in power as well. And this from an engine with almost a quarter of a million miles on it. I would absolutely recommend them to anyone considering this upgrade."
