Muffler bearings? Are they expensive? That takes me bake a long way, we had a good friend in high school convinced he needed new muffler bearings. Seriously, I originally posted that I had heard that you could do damage by running no exhaust headers, but I don't really know. However I do know that if you have a refrigerator on your front porch, you can run an engine without headers. Remember I have done this before, but we did have to mow around car when we cut the grass.
