cats

Hi Guys, my 135i has been decatted from the primary cats, but the person did not have it remapped out of the ecu and i keep getting an irregular misfire for a milli-second because the Check engine light is on and bmw turned it off and it comes back on straight away. I have changed my ignition...

going to be changing my exhaust (manifold back) for a stainless one as my cats are shot, thinking of putting 200 cel ones on and my question is will i have any problems with emissions with these cats thanks

In the near future I'm hoping to replace my exhaust system with a stainless steel system from the manifold all the way back. I'm just curious if the 840ci has 2 cats or 4.

Wanted e38 Exhaust downpipes with cats and lambda probes must be from anything v8 engine Wanted for a 750 but 740 system would be fine as I will be welding them into the original system as mine were cut out and stollen. Many thanks James 07977 502097

Hello, does anyone have both cats available? The oem were replaced by some nasty old tiny ones. Maybe M62TUB44 also fits.

Im thinking of having the secondary cats and resonators removed on E92 M3, will i have issues with the engine lights coming on or power issues with engine, as im not having it remapped. Will i need to have it mapped?

Hello, hopefully someone will place this where it needs to go. E36 318is 1998, I understand I can use a non type approved cat because of its year but the question I have is will a non type approved cat be man enough to pass an mot?

As the title suggests, I own a 2001 e39 530i Automatic - over the past couple of weeks it's been driving like a tractor. I took the car to a specialist yesterday and as I suspected the cats on the manifold are blocked. The specialist has suggested a few things to me: • Replace the cats with...

I'm considering having the aforementioned fabricated for my 645. I've not been able to find any info on anyone else doing this, can I expect de net increases in bhp? I still need it to pass mot emissions obviously

i picked up a very cheap 330i convertible today but it is running very rough ,when driving alongand you put your foot down it doesnt go anywhere and just bogs out and you get a popping from the air filter and it is alot worse when cold but if you are at a stand still and gradually build the revs...

Hi guys, Have had sports 200 stainless cats on my 850 but still fails emissions. I am working abroad and the car is at a local BMW specialist for the MOT, so I am at a slight disdvantage. They say that the nearside exhaust is blocked???, and the L bank is firing ok. Any thoughts of wisdom, this...
