is the other hole blocked off, if so then it is there for an extra sensor if fitted by owner.

they are both fitted with threaded bolts mate ,one at the top next to the bell mouth and one near the end next to the resonator

Sounds like a classic manifold,newage have usually got 2 on the 2nd section of downpipe

djc1

it is the down pipe im talking about mate ?
i havent took the old one off yet to compare

i have an 02 simulator but when i saw the two fittings on the down pipe i wondered if id need two if theres two sensors ?

on a newage you should bung the top one and fit the o2 sensor in the lower part of the downpipe
