Doug's headers fittment

Low is low. My point is to dispel any notion that you're going to get any more clearance with the Doug"s. While you may flatten out that tube it's been proven that you're not going to suffer any noticeable loss. However, whatever you're going to clip with the flange on a Flowtech, you're going to clip with a Doug's just the same.

That’s not true at all. I mean sure, if you’re going across a uniform height speedbump that’s wider than your car that might be true, and even then it makes a difference how close the low spot is to the suspension. The worst spot for clearance is halfway between the wheels if you’re taking speed bumps. But realistically, the ground you travel over is never flat, and the more stuff you have at that lower height the more likely you are to bash it on something. Especially if that thing isn’t parallel with the body of the car. You’re a heck of a lot more likely to snag that length of pipe than the point of a collector.

If your car is lowered and you have low profile tires, you might want to rethink the cheaper headers.

Low profile tires don’t have anything to do with it. My low profile tires are still taller than anything you could get stock. Overall tire height is what you have to pay attention to.
