I have a 04 cobra that came with bbk headers, bbk x pipe and magnaflow cat back. I wasn’t to happy with sound so I bought a pair of Mac flow path mufflers so swap out. Well the inlet side fit fine BUT the outlet part that connects with tail pipe doesn’t fit it seems to be same size as tail pipe. Does anyone know if magnaflow comes with 2.5 inlet and 2.25 outlet seems that’s the only explanation. Now im stuck looking for 2.75/3 inch tail pipes only.
