Why not just a hole in the headers? It will make the car even slower. First question is what you're actually hoping to achieve. If it's just fully hektik noise... maybe consider just not doing it. Lots of money to spend to probably make your car slower and look like a complete tool-bag.

what he said above.. cheapest way would be to get someone to hack in a pipe in from the up pipes - but really not going to gain any performance benefit unless its done correctly and with the stock turbo, the noise may be the only gain..

^ which will cause you more problems then its worth plus when you have a stock turbo and try to overtake someone on the motorway at 110kph its starts going off as there is no lag. Gets annoying very quick

TD04HLA-20T is the one you’d want. Not much in it, but the 19T is just their direct replacement for the stock one. In Aus if I remember correctly they were maxing out at about 210wkw with it. http://forum.liberty.asn.au/viewtopic.php?f=17&t=33036 Is there anyone over there that is happy tuning it?

hey man you can remove the stock downpipe and then you can smash the cat out from the downpipe that might be the cheapest option.. or subtech here have a downpipe you can buy

put a nice turboback exhaust for better performance gains what area are you in?

Yea anythings possible. Just not practical or beneficial for most. You need either two wastegates or a larger one with a separator plate right up to the gate to keep the two header runners separate. Best place seems to be just before the uppipe as space is limited anywhere else. Then either do it the dodgy way and bleed it off to atmosphere or have a rather long runner going all the way back to the downpipe. Is the goal just the noise from an external gate? They sound particularly bad on twinscroll Subaru’s in my opinion. Plus not exactly cheap by the time you factor in the cost of fab, gate/s, adequate solenoid and a tune.
