I am glad its you trying to figure out the WI. It sounds like you are going to get great gains from the research I have read.
Is there so much work involved with the tuning because no one has added WI to a Boxster before?
As far as the cats go, the research I have done shows that turboed cars get some boost and power increases because the turbos can spool faster. In the 996tt there is a power gain by removing the cats. In a few weeks we will know if a 986tt has the same effect.
If I dont get and power gains and just get some sound back, the turbos have muffled my sound a little. I will be happy with just the sound. I need my car to be a little louder to live up to the sinaster license plate.
