Removing the pre-turbo cat would be an up-pipe. I assume this is what you meant. I'm currently stg 1 Cobb with my full tbe and uppipe sitting on my living room floor. The AP has been a good investment and now with street tuner out we should start seeing the mod path widen a little. If you ever plan on tuning yourself then you have a pretty unlimited path with the ST unless you want ECU controlled waterspray/nos/additional injectors.
