I am looking for a pair of headers with an O2 sensor bung mounted on the left bank for my soon to be TPI SBC. any reccomendations? also does anyone know if i get the shorty headers will i be able to use the stock y pipe or do i need to change that as well? (kinda new to exhaust) also does anyone know if i can sub in the bosch type III mini injectors over the ****ty GM multitec injectors? i have the type III in my cadillac and it used to have multitecs in it as well.

 

Most headers should have the o2 sensor bungs, just look at the description on where you buy them from or look at the headers themselves.Any type of after market headers will need a ypipe to match it.If you go with shorty headers you can use the stock ypipe but it will need to be fabricated to fit.
