Doug's D453 Headers

The collector hangs half on and half off of the frame rail at it's lowest point. They are as tucked as an a-body header gets.

This. They're actually about 3/8" higher off the ground than TTI's. Only way to get more ground clearance is to run TTI shorties or stock manifolds.

Here's an undercar shot for you. Passenger side sits lowest, mine is 4" from the ground. But my car sits pretty low, with only 25" from the ground to the top of the wheel opening with 25.6" tall tires. Skidplate on the K member is only 5.5" off the ground. In about 7k miles I've only managed to lightly drag one over a REALLY tall speed bump.
