There are a few causes for the overboost code. It can be triggered from latency of electronic over vacuum boost solenoid, especially when fuel and boost have been altered. The use of a Dawes valve puts an end to that.
Another cause can be larger exhausts causing more volumetric airflow. This can only be fixed with an electronic mod or rewriting the ecu parameters.
Some guys will bang on all day that it has nothing to do with larger exhausts because their vehicles have never thrown a code?... That can only be put down to not all vehicles being the same. Variations in wiring loom resistance, voltages, sensors, engine components ect ect.. Sometimes you get lucky with the right combination.
Fact is if you throw more air down its guts you'll increase the chance of having throwing an overboost limp mode. Going with higher flow exhausts you really need to be careful as it can create a seriously dangerous situation on road.
Manufactures of aftermarket exhausts should really warn their customers of the possible dangers... But reality is they don't know they're causing it.

There aren't all that many sensors that read airflow and/or boost so it's not hard to narrow down. But not many end users are going to go to all that trouble are they?
Bill nailed it on the performance issue above. 3 inch on its own makes negligible difference to performance but can help egts if pushing it. MRT have gone on record saying much the same in terms of performance benefits.
I would find it hard to believe that Mitsubishi wouldn't have an intimate knowledge of all the ins and outs of the stuff they are using to build their cars.
