Does the CP-E Downpipe shown on MPSG have a Catalytic Converter with it when purchased? Or does it bolt onto the OEM Catalytic Converter?
Also if I bought the CorkSport or CP-E Cat-Back Exhaust, does it bolt straight onto the OEM Catalytic Converter?
And lastly, if all the answer to those questions are yes, does the Hi-Flow Catalytic Converters shown on MPSG directly replace the OEM without having to do any welds etc.
So mixing and matching is possible? The system doesn't require of ONE specific brand to be fitted for the whole Turbo back?
For the Mazda6 MPS btw
