Another vote for Doug's here. I never used the TTI's though. I have two sets of Doug's. They have nice thick flanges, and are heavier than the standard headers I've used in the past. Look on Amazon before buying. I found an uncoated, new set there for $375!! Not sure if it was a mis-print, but they sent them at that price. I had them Jet Hot Coated after fitting them to the car. Good luck.
