I have had 2 sets of headers on my car, one set came on it and a replacement set I put on, both I believe are from SS. The #3 and #7 tubes hang low and scrape the ground all the time, I will saw my car is slightly lowered by about an inch..I believe the CAT design has the two lower tubes parallel to the ground and side by side thus tucked up a little better, this is info I got from the TIGER LIST. At present CAT doesn’t have these in stock.. I have had my stock manifolds jet coated and am thinking of installing them and forgetting the headers all together. I run stock exhaust so I’m probably only loosing a couple horses anyway.
