newage decat exhaust help
 

hi people iv used the searh facility with not much help. iv recently bought a full exhaust for my 03 sti. it came of an 03 sti the boss for the lamda closest to the turbo has been welded up so i cant put a lamda in it. it must ov run fine in the one it came of and has been fitted for 2 years. wat shouild i do about it? also wat are the 2 sensors in the downpipe as i was lead to beleive the lamda was in the up pipe? any help would be great thanks tony

sorry..typed total rubbish

right then update iv fited the exhaust my car only had one sensor in the downpipe in the cat it didnt have on in the turbo elbow i dont know if its suposed to? but the downpipe i fitted to it had a hole for one in the elbow but it was blanked off. iv fitted the second decat with no cell light yet thanks tony

On a newage STi your first O2 sensor is in the headers - just before the up-pipe.The other sensor is at the end of the downpipe a you've already found out.

It was only on classic cars that the O2 sensor went on the downpipe mouth.

The blanked off hole on your new d/pipe may be fit a wideband O2 sensor when mapping - or the supplier uses a common part mouth section and just welds the hole over for if its for a newage car.
