cats

going to replace the cats with some aftermarket ones.Need to know the diameter of the down pipes please. 1999 e430 estate preface lift model single cat on each down pipe cheers:thumb:

Hi guys looking for some cats for an e270. They don't have to work as I plan on decatting anyways. Thanks :thumb:

Hmm, MOT failure last friday on emissions (0.4% rather than 0.20 Max. . .) so the guys say I need new Cats. MB price is horrendous. Anyone know a custom cat supplier, or even after-market for a C32? I'm assuming C320 doesn't fit. . .? I'm not necessarily terrified by the thought of custom...

Is this something EuroCarParts get involved with, and if so, how much are they?

Exhaust CATS and upcoming MOT changes... As we approach the revised MOT I think 01/2012, is there any more knowledge about the CAT situation (specifically regarding those with multiple CATS and 1 or more having been removed) i.e.: "No, your car still has a CAT fitted, regardless of how many...

Having trawled through these pages, I fear one of my CATS is breaking down. I have a rattle from the exhaust that only appears when hot. I've had a cursory look for loose brackets and heat shield, but they seem OK. It was getting dark so I'll check tomorrow daytime. If I find nothing, I'm...

Hi, My 211 E500 has developed an exhaust rattle over the last 1000 miles or so. It's just passed the 100,000 mile mark. I'd like to think it might be an exhaust heat shield or something but suspect it may be one of the cats. Has anyone any suggestions on (a) how to diagnose? (b)...

I need to get cats fitted to my S600 for it's first UK (The car had striaght through pipes fitted when I lived in Dubai), and it's seems the best price is from cats Direct, which is a very reasonable 350 inc vat for the pair, although that is for the cermic ones. Does anybody have any...

You know the story, out to a mates for dinner, come back to a car that now stinks the garage out..... How do you stop cats from using your car as a toilet, is there a secret out there???

Hi, I have two of the original cats from my previously owned CL500, I also have both of the back boxes with original tips for sale! Cats £100 for the pair Back boxes £40 each These items came off of a well looked after car with only 64,000 miles on the clock. Please PM me if interested...

Hey guys, Can someone pls enlighten me about the benefits of one way over another? If my car has two pairs of cats, would it be better to remove second pair or remove all four and fit two hi flow ones? Thanks.

Hi All, I'm either after a full but damaged ML500 to break or a full exhaust system with cats please. If anyone hears of anything then please let me know, Cheers, Rob

I thought given some new photo's are available, I'd treat this modification to it's very own thread. The modification of headers and cats was very much a last minute decision but as you'll probably know, my car is out in Germany this week having the final adjustments made to it's suspension...

I've done a quick search on here - i think the diagnosis may be a cat on it's way out, but thought i'd see what the consensus is. When the engine gets warm - i.e. > 80deg, with the windows open, when accelerating then i can hear a tinny rattle - only seems to happen up to about 1800rpm and...

I've had the nasty, (17Kg!) rotten centre silencer chopped out and replaced with straight pipe to the nice AMG backbox. The guy said "I nearly chopped two of the cats out but I didn't". He went on to explain that on each of the 2 exhaust pipes there are 2 cats in series. He said I could get...

I've seen mention that early R129 500 SLs, 1990 vintage, do not have cats. Is this correct? If so, when were cats added to the exhaust system? Thanks.

I know this is a question that never gets fully answered so maybe I will be able to shed some light on it. I am going to remove my main catalysts this week(hopefully, depends on the weather LOL). I know there's not much to be gained by removing them and maybe even a little less torque, but my...

Has anyone had a after market cats fitted to this model, can you tell me if you have felt a difference with performance and noise levels ????

I have just bought a 1998, W129 320 & suspect that the cats on the nearside are knocking, firstly is this typical on W129's , 2nd should they be replaced straight away if knocking & 3rd what kind of money are they to replace them. All help appreciated guy's

Hello wonder if you could help out a newbie. Have a e430 estate and rattle from under car has been diagnosed by local garage as cats gone kaput. Can anyone point me in the direction of cheap replacements? Also could do with a couple of trim parts and wonder if there's a good source of...
