If you have long tube headers, they are going to scrape the ground at some point, especially if you have a lowered your car. If it's at stock ride height, you might scrape on a giant speedbump, but that's about it. I have a set of TTI's on my big block in my Challenger. They hang low, but guess what? I could care less. You just have to drive like you have some sense, and avoid speedbumps, which isn't that hard. BTW, my car is in the weeds too.....
Congrats on your purchase!
(to the oringal poster) They should bring many good years of service.... Just make sure to keep'em clean and somewhat dry....I'm not a huge fan of Jet Hot, seeing as how every set of headers that I have ever had coated, rusted.
