It is, definitely, possible to do this. As usual, the first example is
going to be very expensive. However, something along the lines of a
custom header going into a modern high-flow cat would be legal (except in
California, where CARB approval would be required) and could net a
considerable increase in power - perhaps as much as 20HP. This is the
sort of thing that ought to cost $1000 or so but in practice will probably
cost a lot more. :}

Really. :} When will the specifications on this be "officially" coming
out? Have any cars with the upgrade been produced?
