V8 Downpipe, one or two cats?

(1/6) > >>

Reggieroo:
I've been told two different things regarding the down pipe cat. One chap has said that it only has one cat & the other side is a a silencer & another chap has said what I thought that it has two cats one either side.

My thinking is that you can't have one cat on one side & not the other on a V8 down pipe as one side will be more restricted than the other + it has two lambda sensors, one on each side.

Does anyone know for sure then answer to this question?

cluffy:
two cats

craig_midz:
yep as above 2 cats but cut em out ya v8 will love ya for it mine does an it passes its emissons as it still got lamba sensors in

Reggieroo:
I've already cut one out, thats why I was asking as I was told by one guy I only need to do one  :?

craig_midz:
what i did was buy a rangie 3.9 downpipe without the cats in an found 2 nuts that the lanba sensor would screw into drilled 2 holes in downpipe an welded nuts onto downpipe looks orginal then an never had a problem all it did was give me a bit more of a growl out of exhuast an a few extra ponys
