It is the right idea except for the wastegate discharge need to be much longer before it re-joins to see any benefit (they say about 18"). Everyone seems to agree that the stock o2 housing flows enough for the stock turbo at any boost it can develop. The downpipe ("dump back") does make a huge difference in response and horsepower so it is highly reccomended
