Regarding rust no one has ever posted on a failure.

For some repairs parts of the system often have to be removed, this can cause early failure of the welded pipes

Hi,
My 1999 C43 AMG has done 133,000 miles now on the original exhaust, though it has been repaired by the look of it, where the pipe enters the silencer box on both the middle box and the tailpipe have been welded none to prettily either, and there is clamp which ties the 2 exhaust pipes together which broke off. The boxes are really still very solid and sound.

Thanks guys, I don't have anything to worry about yet then,

IMO the OE exhausts are excellent and last very well. I had to have the hanger bracket re-welded on my W21o back box however the steel is so think that it MIG welded no issue at all. I'm also fairly sure that the exhaust on my S123 from 1986 is original and only has the downpipe to mid section bracket issue that needs some attention.

Really depends on your driving patterns Short journey syndrome like elderly lady driving 100 yards to the shop to buy cat food twice a week is not good for the exhaust. Build up of water vapour turns into a mild acid which corrodes the system fro the inside out. Once the system gets up to temp on a good run the acidic water is evaporated away. The rover engines are quite noticeable for creating this, next time your at a set of light and there is a rover in front of you check the exhaust as they set off, it comes pouring out. So if the back box is 2 inches deeper than the tail pipe height. . . how much water must there be in the exhaust. . . . lots.
My car is a 1998 W202 and still has the original system on it. But I do an 80 round trip to work every day.
Bosal put a drain hole in the endplate of the back box especially to drain out the condensate.

My 96 202 did 175,000 miles on the original exhaust, and I only had to change it because the cat collapsed internally, the rest of it had no significant corrosion. Conversley my wifes Y reg 203, main silencer hanger was completely corroded through and failed in just over three years (just about 25,000 miles).

Driving habits are pretty steady, I do about 100 miles a day with few short journeys. Everyday I have a reasonable run on a bi-pass or motorway so there should be very little water build up in the system.

The reason I ask was the exhaust seems to be getting louder and rougher. I wondered if the exhaust was starting to go. Its only two and a half years old and done 45k miles and I have gone through exhausts quicker on previous cars. Its also an opportunity to put a performance cat and back pipes on perhaps,

Have you checked to see if there are leaks on the down pipes etc, its a distinct putt putt sound when standing near the car, and one can often smell it

 

[polarbear]

I have had a quick look and can't see anything obvious and there is no putt putt.

I have noticed a slight reduction in power and MPG is down 15%, not clever seing as my car was last serviced about a month ago.

I may just drop her into MB and have a quick check up,
