De-Cat/manifold

[possel]

i have been looking at a few de-cats but they all seem to be a single one thats well after the manifold and bolts into the centre section, for some reason on mine it has 2 cats on the manifold (one either side) im really quite confused by this?????

Is yours auto?

[possel]

yeah unfortunatley it is :(

Cats are part of the header assembly on the autos. You're stuck with them unless you want to get secondary headers custom made. No one makes off the shelf units for them, only the manual which has a single O2 sensor. The auto has two, one sensor for each cat.

You could always take the manifold off and gut the precat!!

all you need is a down pipe from a manual tezza

it will fit the same as the cats but you wil only use 1 lamda sensor

[E910]

You're asking for trouble only using one of the oxygen sensors. The closed loop ECU will pack a sad over it

E910 where did you source that info from, looks like it could come in very handy.

managed to get a manual tezza downpipe, goin to put a bung in the orignal lamda sensor boss, then weld in 2 new lamda bosses then fingers crossed should run fine. cheap de-cat mod for all the auto drivers that want to get rid of them :D

i using mine with just one lambda sensor no problems ere
