Re: What's that rattle?

[Jon Blake <jonb@u.washington.edu>]

Two comments, one possibly germaine and helpful the other likely to get me
flamed. One, exhaust rattles, etc. are difficult to pinpoint. I thought my
cat innards were going when actually it was the exhaust pipe bumping
against the rear diff.  Now for the other one: why take out the cat when
you know that your car's exhaust is cleaner with it in regardless of
whether or not it passes inspection?
