I believe I still need cats in my area. Although, there is not an emissions test as part of yaerly vehicle inspecton - they are talking about starting it in the near future.
For the moment, I was only looking at replacing the downpipe as it has a hole in it. However, if I can afford to change the hole system I will. Is that necessary, or will changing just the downpipe also give some HP gains ? |
