It is strongly recommend to use the RoadsterSport SuperQ Header version muffler with this header because it was designed to handle the sound level of the header and our standard midpipe. Most other mufflers will be too loud for most folks with this header change.
Our outlet is 2.5 inches. Intended for use with our RoadsterSport midpipe and RoadsterSport SuperQ exhaust (special header version STRONGLY recommended) so you are getting 2.5 inches of flow all the way.
Factory first O2 sensor is in the OEM header and stays in our header - included with this header is a short o2 wiring extension so that first sensor can reach the bung down below the collector. Factory second sensor in the midpipe should be moved after the factory midpipe converter to avoid an engine code (our RoadsterSport midpipe provides bung in that location for this reason). That second sensor reaches its new location without use of extension cords.
