Casual inspection of the exhaust system appears to reveal a not-so-easy
project when it comes to bolting and unbolting cats since they're part
of a larger section. I've always been curious as to how the car would
run with gutted cats or "test pipes", and I seem to recall varying
opinions on the list.
The cat on my ur-Q was somewhat clogged but was very easy to unbolt and
reinstall, so it made a very substantial difference when I er,
accidentally knocked out the guts of the cat in an attempt to improve
Is there any consensus on

piping but keep the remainder of the system stock and
2. is removal/replacement as difficult as it looks compared to the ur-Q?
