I doubt that this figure is right unless you skip the catalyst and the rest....

MTM is offering a silencer which will add another 5 hp for a standard car or
chiptuned car.  I'm afraid this is the more correct figure :-(

I had a 92 Subaru Legacy Wagon 2.0 turbo which was chiptuned from 200 up to
295hp for street use by a rallycross racing tuner here in Norway (Simco). In
order to achieve this power, I had to replace the stock catalyst with a
racing catalyst (which set me back some 1500$).  The racing catalyst in
itself did not give significant power increase, but the reduced back
pressure allowed him to modify the chip more. (turbo pressure, ignition
timing, more fuel etc.)  
What I am trying to say is that a new exhaust setup does not give
significant power increase unless it is matched with the engine management
to take advantage of the reduced back pressure.

Another thing is ofcourse that it adds to the image of the car with some big
bore tail pipes and matching sound..... :-)  but for power, well....
