Will the Rinehart HP45 Slips fit on these?
By Anon.
Also, will 18mm sensors fit, or will they need to be drilled out?
Answer QuestionSo long as those Reinhardts fit the OEM headers, then you should have no problem fitting these PCX headers to your bike. As for the oxygen sensors, these pipes ship with a pair of 18mm to 12mm O2 sensor bung adapters, so you needn't do any drilling to fit those larger components.
