If the car sits any lower than stock in the front, or if you have soft torsion bars, you'll cringe every time you go over a speed bump with the cheap headers. Not worth it IMO.
I had some on a 71 Dart I drove every single day. It sat stock ride height. I never scraped the headers on anything and I drove over many speed breakers. They do hang lower than other header makes like Dougs and TTI but I knew that going in and I left the car at the stock ride height. Plenty of guys run these type headers with no trouble. Yes, if you hang your junk low in the weeds and run short tires, you're asking for trouble, but otherwise they work well.
