Stock vs. Mystery Exhaust
Admittedly, the "mystery" about the header pipe on the 750 Sport is in all likelihood one of three possibilities.
- The header that came on the 750 when I bought it is matched to the Fast By Ferracci cans.
- Ducati switched headers as they went along, meaning both headers are stock, only the larger diameter headers are later.
- The header that came on the Sport when I bought it is off of a later motorcycle (probably a 900 Supersport).
For reference sake, the stock header is 35mm diameter on the manifold side, and 40mm diameter on the silencer side. In comparison, the headers I am getting ceramic coated are estimated to be about 10mm larger in diameter. I'll measure them once I pick them up from the coater.
There are some other differences. The stock set (pictured) have a gusset where the exhaust diverges. The other have larger diameter pipes at the diverter and there is no gusset plate. I did not think to look for a part number on the pre-coating header before I handed it over, but I will look for one when I get it back.
