Newly passed son came home last night in his £1000 Citroen C1 and said 'it's making a bit of a rattle'
Quick inspection and rear exhaust is hanging off!
Anyway - when i was his age it felt like I had to get an exhaust replaced about every other year, I don't remember doing one for about 20 years now. What's changed, have materials got better, less salt on roads, something else? I've had my car 7 years and 75000 miles and (oh, that's ****ed it now) not a hint of any exhaust problems.
Q2 - how much poorer will I be later today?
Aluminumunised steel I think. That may be a misspell
Much more use of stainless and aluminised steel.
Many reasons, Competitors start using it, so we need to, Warranties are longer, Exhaust gases are tending to being hotter now, more use of turbos (heat/vibration), DPFs, catalysts, NOx traps.
Quite a lot of them need to be made out of stainless or at least a higher grade steel, so it's cheaper to just do the whole thing in stainless. Rather than adding joints.
I know a few manufacturers have just done a wholesale switch. Get everything in stainless (or aluminised) to save money on materials.
Wife’s ford cmax exhaust is knackered (car’s got close to 100k on the clock) got quoted approx £2k from nts. Catalytic converter’s are expensive it seems!
A dodgy back street garage reckons he can bodge it for about £200 with a bit of welding and a new down pipe!
What’s changed, have materials got better
Yes.
Materials, either stainless or something else not sure. My Passat did 160k miles on the original exhaust; the Prius needed a rear section after maybe 100k I think.
how much poorer will I be later today?
Not much, exhaust sections were pretty cheap last time I had one for a cheap car - but that was a while ago as above.
get a custom titanium system, will last a lifetime.
And only cost you a couple of thousand 🙂
Had this conversation with MrsMC the other night - not had to worry about an exhaust for 20+ years.
My Golf has an almost entirely stainless system, but for one part. There's a stoopid mild steel band that rusts through every 100k or so, so I'm about due my third. This should go in the annoying things thread...
Current car is 10 years old and on 145k. Original exhaust still looked good when I was underneath it a month ago doing an oil change.
Last car I had to do any exhaust work on was a P reg Punto, when it was about 6 years old.
Don’t panic you can still buy crappy pattern parts that only last a couple of years.
Do remember you can repair. Our Ibiza front section included the catalytic and Flexi pipe, so was £1100.
Or the local place welded in a new Flexi pipe for £80 and it was fine for 4 years until we sold.
Only exhaust I have had to change in the last 20 years was on the Shitroen C3 Picasso disaster zone that only had about 30k miles on it. It had rusted through where the exhaust meets the rear silencer.
I guess lots of short journeys where condensation sits in the exhaust & doesn't get evaporated off kills them from the inside?
Current 18 plate Leon is on 65k miles on original exhaust.
Wife's 12 plate Ibiza is on about 150k miles on original exhaust
My previous 03 plate Ibiza was on its original exhaust when I got rid of it with 272k miles on it.
Cost-wise I guess £165. Probably miles out.
Do remember you can repair.
Absolutely +1 (assuming that it's broken in a section of pipe and not at a weld to the box)
As mert points out ^^ ...better materials
It had rusted through where the exhaust meets the rear silencer.
You've seen it then 😉
Engine side pipe into the silencer - it has a deep throaty roar now from its 1.0ltr engine that I'm sure a 17yo boy would love to keep, but the clanking as the rest of it bounces up and down ruins the effect.
Local trusted indie T&E place has got it and will try to fit it in around other jobs......
Phoning round Kwikfit can do it within the hour.
Aaaarghhhh, conflicted!!
Deisel engine cars don't destroy exhausts as badly as petrol engines. Iirc something to do with acidity of burnt gasses , and vapour products on start up corroding steel. If the car doesn't get fully hot the moisture in the system sits in the low parts and rots it .
Plus the exhaust on most cars is fully exposed to road salt and can be attacked by speed bumps so they have a tough life.
Deisel doesn't produce the volume of moisture or the same level of acidity so the exhaust system lasts for much longer, sometimes the entire life of the vehicle
If it's an older car worth checking breakers for a replacement part. Local exhaust place wanted £500 for an exhaust on a car worth £300 a couple of years ago
I thought it was just my Honda, being a Honda, was the reason my original Exhaust is still going after 15 years 😄
I guess places like Kwik Fit are still in business as they can still con people into new tyres they don't need. Probably still try to flog them an exhaust.
The C1 has a common failure point on the back section. A replacement was £40 (5 years ago) and only needed to undo 1 bolt when it happened to my partner. You can even do it by reversing the rear right wheel up a curb if you don't have axle stands.
Jag x type 150k miles 56 plate still on original exhaust.
Vito van 100k miles 63 plate still on its original exhaust.
Ford cmax 120k miles 06 plate still on its original exhaust.
Manufacturers have certainly changed something in the last twenty years, for the better, I haven't had to roll around under a car cursing at the exhaust for many years 😁
Actually only ever done 1, and that was by choice - my E30 has a manifold back Scorpion system. The other halfs '13 FL2 at 110k has the original, my '08 Defender at 140k has the original (though the rest of the vehicle is like Trigger's broom) and the '17 Mazda CX-5 at 50k has the original (though hardly counts I guess). There's also a '03 Transit Connect lurking in the corner of the yard which appears to be orignal too - it's certainly not coming off in a hurry if I wanted it to! Mum's Polo on the other hand - '12 IIRC - has had many replacement exhaust parts including 3 silencers. Seems like the baffles in them decay really quickly.
Not just exhausts but rust in general, my parents live by the sea and in my childhood, cars used to fall apart quite regularly. The last volvo survived about 20 years however.
Haha rust. Son is having his MX-5 de-rusted at the moment. He knew it needed doing when he bought it. I knew they were bad but I didn't realise how bad!
OEM exhausts have got better, both in materials and the fact that most are now a single piece with no joints from the catalyst back (and the catalyst itself is adding a fair amount of heat to the exhaust gasses). My c-max was scrapped at 150k and it was still in good condition. The Berlingo was also original at 165k, albeit the back box was just a perforated box shaped piece or rust.
Short journeys kill exhausts as unless the whole pipe gets consistently >100C then you end up with water condensing and collecting around joints etc.
The OH's fiesta is on it's 3rd back box, and that's held on by a series of adapters/clamps as the corrosion creeps up the mid section each time. Cheap aftermarket parts + her insistence on driving around town.
They rust on the outside once the galvanized/aluminized coating is gone, but it's rusting from the inside out that kills them.
Going back 7-8 years, making the original system 8-9 years old, my C1 replacement exhaust cost around £150 (cat back). 3 years later, the silencer was starting to rattle. Just in time to get it p/x-ed for a newer car

Under the paint and primer, the wings on my Leaf are black, which looks like some kind of epoxy paint.
What’s changed, have materials got better, less salt on roads, something else?
Back in the days when tetraethyl lead was added to petrol they also added dichloroethane or dibromoethane to scavenge lead oxide deposits from the engine. These additives broke down in the engine to produce hydrochloric acid or hydrobromic acid which contributed to exhaust corrosion.
I was quoted about £850 supply only for a section of exhaust on my zafira tourer. Couldn't get said section from pattern part supplier, main stealer only. I had a full stainless system made (cat back) and fitted for £300, which has a lifetime warranty. Worth a look? Mine was from Tony Banks in Leeds. Slightly noisier is the only downside (dad racer)
The manifold to cat section snaps also on Aygo/C1's. Had to have a full system, manifold back on our 12 year old Aygo - best part of £800 with two sensors and a cat.
Agree on Tony Banks above if you're anywhere close - had a full cat back stainless replacement for my Aygo for about £300.
Nasty mild steel pattern parts were about £200, and would have had me crawling under the car for half a day to fit.
back bit only. Not Kwikfit. £189
In the same week as a £1485 insurance policy, his motoring is costing me a fortune.
Taking the sulphur out of fuels will have helped. The steam in exhaust used to be sulphurous acid.
Same here re:insurance on the Aygo - 1 month costs as much as a year on my car, with two youngsters on the policy.
Thinking about it, we had 3 or 4 back boxes on our Aygo over the (10/12/14?) years. They're so cheap and easy to fit that I barely thought of them as an expense or problem along the way
I honestly can’t remember when I last had to replace any exhaust parts or full system. It might have been on my old Morris Minor, or one of the other cheap cars I had between that, around 1974/5, and my Puma around 2002. There’s only been the Octavia and now my Ford, so hopefully that won’t need one for the foreseeable.
First question is "can I fix this with a baked beans can"? If so, then fix it with a baked beans can and no fewer than 6 jubilee clips.
It was the exhaust failing that pushed my work colleagues Porsche Cayenne into 'beyond economic repair'.
The silencer and exhaust outlets are ~£2k and only available from Porsche.
I bought the car for £500 and repaired it for £200 with as good as new parts from a local Porsche specialists breakers!

I went to Kwik fit when the exhaust needed doing on my old Focus (needed it done at short notice at the weekend). It must have been at least 12 years old and on 150k miles at that point.
Managed to just catch them as they were closing on the Friday and the guy I spoke to gave me a silly price, maybe under £100 for the whole thing. I went back in Saturday for them to do it and he said he'd given me the wrong price, but at it was his mistake they'd honour it. No "oo, you need new brakes" or anything either.
