Here's the story: I was given a friend's one owner 78 Pinto Pony with 37k a few years ago and have been working on getting it roadworthy ever since. I think I'm finally at the point of getting it to the state inspection (last one was 1993). They may fail me for the holes in the muffler. Of all the cars I ever owned, I can't remember ever having to buy a new muffler or exhaust system. I'm kind of out of date on what the usual cost is. What should I expect to pay a shop for an exhaust system from cat back? Any recommendation s in the Flower Mound/Lewisville/DFW, TX area?
