Pre-Cat 1.8
well just wandering if any one has removed the pre cat of the manifold and if it made any diffrence to the perfomance at all as i seem to get mine to glow if i boot it hard and will i need a new manifold
|
Id be interested to know about this aswell.
Im sure you can remove one of the cats and it will still pass the MOT. |
that was somthing else i wanted to know will it still pass the mot
|
buy a janspeed manifold, have removed the pre cat before and didnt notice a difference ( on a 1.4)
|
i never had one on my 1.4 rover but im wandering if this pre- cat will restrict the 1.8 by much
|
doubt it, the pipe bends are crap on the standard manifold anyway
|
so if i upgrade my manifold and remove the pre-cat will i gain any thing
|
You will get gains then, but Janspeed manifolds are quite expensive.
|
just been told today that the 120 has high emisions and if you remove the pre-cat you can fail your mot
|
the pre-cat is inside your manifold, so if you replace your manifold with a janspeed item it won't have one ( however you will need a janspeed sports cat or decat pipe or your cat custom made to fit )
doubt the 120 wuld fail without a pre-cat, however have known them to fail without the proper cat |
