Topic: Exhaust System Longevity-Mufflers, catalytic converters

[Max439]

Anyone can state their experience with their car's exhaust system longevity. I have a 1986 Audi 5000/200 Turbo Quattro, 305,000km with original exhaust system. One rubber hangar replaced 5 years ago. Had new donut installed between catalytic converter and pipe 2 years ago. Hangar welded to exhaust pipe January 2010, which was found during scheduled oil change at my trusty mechanic.  Anyone lost any exhaust piece? What kind of car? Where fixed?

Oddly, I have a whole cat back for an '87 Audi 5kcstq sitting in my garage.  Just the other day I was noticing how well it's stood up.  As I recall I went through a few doughnuts as well.

Our '03 Subaru Outback recently suffered it's first dragging muffler; rotted through at a 2 bolt flange.  $80 later it's sleeved, welded and good to go

A few years back I had to replace the cat on my Audi 90q20v, it fell off on an off-ramp, never did find it.

'05 Protege5 with ~ 235K on the clock...OK so far.

I have a 1998 Volkswagen around 200K with the original exhaust system.   No parts on the exhaust system have been replaced yet (fingers-crossed).  Being my daily driver for the last 12 years, the pipes and hangars look pretty rusty, the muffler is shiny in some spots.

Before I had a Nissan, I had to replace the muffler at least 3 times due to rusting off.  I would patch holes on the muffler and pipes with old Coke cans and metal straps.

On all the MB's I owned, I only had one exhaust repair, thanks to some road debris.  They all lasted past 400K without problems otherwise.  Excellent quality and durability.

Every other car I've owned has typically required some sort of exhaust repair in the 250-300K range.  The Forester, close to 250K now, has just developed a small hole somewhere that I haven't attended to yet.  The dealer tells me that you have to replace the entire system and the cost is enormous.  Of course, I'll take to an indie repair shop and spend a tiny fraction of that.

1999 Honda CR-V

It needed a new catalytic converter in the 9th year. It was totally clogged due to the inside disintegrating.

While I was at it, I replaced the downpipe prior to it and the B pipe after it just so that I wouldn't have to touch the exhaust system for another 9 years or until the car died at around 18 years. Those pipes and stainless steel resonator were fine, but the flanges were getting a bit thin due to corrosion.

The stainless steel muffler is still original and looks like the day the car was delivered.

Parts: all OEM from a discount Honda dealer in the USA.
Work: done right by myself.


1995 Porsche Carrera

The complete exhaust system is stainless steel and completely original.
