I'm limited on what headers I can use because of the Tiptronic transmission. The issue is the coolant hoses going to the trans. I have found one one header that I can use with this car and it comes with a 200 Cell cat.
Porsche Boxster 986 / S NHP 200 Cells Exhaust Headers - Maxspeed-Motorsports
So a ROW tune isn't needed. I just want to be able to open up the intake some more and the 550 Special Edition tune would allow me to do that.
