[911buff]

While researching on how to modify a stock muffler to a sport, I came across two articles on 911 mufflers but nothing on 914 mufflers. Two questions; First, is the construction of the 914 2.0 muffler internally the same as the early 911 muffler and second, if not, does anyone have a DYI procedure for a 914 muffler? I am assuming the internal construction of the two are the same but usually when I assume, bad things happen. If the internals are similar, then the 911 procedure will obviously work...just want to be sure. Thanks!
