yep it was on my 93 until I replaced the whole exhaust tubing. I went from the stock 2.25 inch to 2.50 from the bottom of the header all the way back. The guy who did my exhaust was able to get rid of that dimple thing, which seemed like it would restrict exhaust flow. Its been awhile since I did the new exhaust and I didnt loose any low end power or anything. So loss of back pressure was not an issue after removing it...

Ok I'll ask the question.
What driveshaft needs that dent to clear?
Unless Im mistaken my driveshafts are on the drivers side and the exhaust is on the pass side

I know I got a dent pretty much the same to that when I bottomed out my stock suspension. Finally redid my whole exhaust system.
