In the UK only cars registered after July 1993 require a cat. This was a
manufacturing requirement, so even then, you can remove the cat so long as
your emissions tests are satisfactory (they are a little more strict than
for pre-07/1993 cars). Emissions-wise, my car has always had very good
hydrocarbon results - much better than more modern cars with cats (I made a
blind bet at work, once surprised even myself how well my old tank did).
I've even removed my failed EGR system and the last emissions test (done in
March) "ruled" :) I think it's a fair test, given that the results are the
important part.
My car has never had a cat, but this exhaust has really opened it up -
throttle response is much better, turbo lag dramatically reduced and it's
still not _that_ loud at part throttle ... Compared to the standard system.
I don't know if that is the increased bore (2.25" to 3") or losing the
middle silencer.
The exhaust is from Sweden, where their emissions and noise requirements for
cars are more strict than in the UK and it's definitely a popular exhaust on
classic 900s over there.
