About 3 years ago I replaced the muffler on my 98 Civic with a Honda muffler I ordered from somebody in cyberspace. .. Because it looked simple, I just did it without the aid of a Haynes or Chiltons or whatever. Apparently, there is an easy way and at least one really difficult way to do it. It now sounds like there is a problem further up the line and its about 20 degrees outside now. Are the muffler chains going to do a hatchet job on it using inferior pipes of their own creative, fanciful design? Is this the kind of job a local mechanic would rather not get?
