Depends what you want....
Power
Change the whole Turbo Back Ext (TBE). Bigger pipe size, more power but less torque and vice versa. If you are going for stage 2 map, you need to change TBE to 3" to maximize your output. If you keep it at 2.5", you get enormous torque and problem lower HP
In general, the less restriction the best for Turbo cars cause you don't need back pressure like the NA cars and some goes to the extend of de-cat.
Some grunt and looks
Change the Cat Back Ext (CBE).... didn't really measure the performance gain but heard someone saying change CBE can get better power.... maybe stock flow is not good? Don't know... havent seen any data that backs it other than butt-dyno.
This is long story cut short la....but always decide what you want before you do this.... ext mod can be very cumbersome, today you may like a bit more sound, tomorrow you may find travelling at 160km/h with droning cabin driving you nuts - mine went from loud, to soft and loud again and back to soft! LOL and its not something you can put it into a forum thread because its really very subjective.

They adjust your door so that it is tighter..... I did it before cause I complaint about the wind noise on my MK5.
