Daihatsu Sirion exhaust fix - Not what I thought...

Miss Daisy, our 1998 Daihatsu Sirion M100, has developed quite the exhaust blow. Sadly, it wasn't what I thought it was, hence the assistant of Tim at Cambrian Classics was sought.

As others have commented, surely you can adapt aftermarket exhaust sections without replacing the whole thing. One car waiting for parts, one car can't be driven in bad weather, one car drinks too much, but at least you still have alternatives.

[@Isaki138]

I'd have just bought a cheap muffler that fits, sawed the old one off and clamped the new one on. Less labour and no crusty muffler.

[@linseyyoung1772]

You can get sleeve joints to join sections back together if you've cut the exhaust. Just because manufacturers decided single piece exhausts were a good idea, doesn't mean you have to keep it in one piece 😉

I was going to make the same comment.

And they don't provide sufficient hangers so the exhaust moves too much and breaks the hangers and/or welds at the box eventually.

Tim to the rescue once again! Glad he was able to fix that up for you on short notice.

[@johnnorth9355]

Being able to join two bits of metal together by welding is a right of passage we should all take. Buy a Parkside Flux core welder from your local Lidl supermarket and after a couple of days of practice you will become a welding god in the HubNut household !

I just randomly started watching this channel and it just now dawned on me he is basically british Aging Wheels. And I love it.

[@HubNut]

That's a fine compliment! Love Robert's work and I have part of his bus.

[@Mickhanic-garage]

If the silencer has broken up inside that could be causing a partial blockage and back pressure. That could explain the lack of power under load

[@HubNut]

That's a point, though it seems to be flowing well.

[@426baron]

Very interesting. Is there a way to make sure something like that is/isn't happening to one's car ? Thx.

[@Kevin75668]

I've seen catalytic converters do that, mostly on ones that have it mounted vertically below, or as part of the manifold. If the broken chunk is wedged in place firmly enough, it won't even rattle.

[@Mickhanic-garage]

I had an old bread van Polo years ago it would drive fine but on hills it would slow down the more you pressed the throttle, got that bad you heard pressure escaping when you turned it off.. New rear silencer it flew after that!

[@eddiejones.redvees]

[@alansmith1770]

Miss Daisy sorted. Tim at Cambrian classics is really good.

[@anthonystevens8683]

Many thanks to Doctor Tim for performing minor surgery to bring Miss Daisy back to better health. I'm sure the appropriate pain killers/anaesthetic were provided to her before hand. Many thanks Ian and Tim for the progress. From my experience some longer exhaust systems can be fixed without a complete replacement by removing and replacing parts of the system adding sleeves to join new bits to old but I guess this varies a lot from car to car.

[@menditman2004]

Hi it’s great you could save the exhaust for the time being, especially as this time of the year finances are tight, I’m finding the same but I did stock up some parts I need for my many projects when finances were better, so I have a lot to get on with. But big cold unit isn’t to inviting atm 🥶. I do think this year should be the time the Hubnut channel introduces a welder, with older cars as you know they are really a must and it would make great content. Good video 🙂👍

[@daniellee9015]

Absolutely brilliant video Ian ❤️👍 it's great having good friends who can sort miss daisy brilliant

[@donnysweekendvanlifetravel7854]

It's cheaper and just as easy to buy a welder and practice, if anyone wants lessons I've done it for 30 years 👍👍👊👊

[@martinneumann7783]

Hello Happy! I replaced the complete exhaust on my C1 last year. No welding possible anymore. One sill welded last week; both sills waxed like Tim did on Miss Daisy. I have to take her out for a ride when it's dry again... Have a nice and save trip everyone out there!

[@scottishcarenthusiastsandtrain]

Great to see Tim work his magic on Miss Daisy. Great video as always.

[@split_pin]

At least you caught that before the exhaust broke off there completely and causing more damage. Good save.

[@richardhemingway6084]

Those one piece exhausts seem common, as they come from the factory. I recently replaced just the rear box on a Fiesta. They do make after market, rear silencers. Just had to saw/ angle grind, the old one off. I just had to offer up the new one, to find where to cut and allow sufficient fit into the flared end of the new replacement. Fitted perfectly, with clamps, no problem.

[@davidjones332]

I think the Sierra was one of the first to do this, as the factory fitted the exhaust before the rear axle. You had to chop it up to get it off, but all the replacements came in separate sections.

[@BPJJohn]

On the old Honda Concerto my dad drilled holes in the back silencer to drain out any excess moisture to extend its life, somewhat worked.😆

[@johnlladron735]

Thanks for the vicarious tinkering video, Ian. You don't need to replace the whole exhaust system though. The box looks like something that could be got from a number of generic suppliers and then sleeve the pipe. The damage inside the box is more than capable of hindering progress and strangling the car.

[@jarlrise]

Just noticed the same car advertised for sale here, with 4WD ! Never seen that before, no idea they came with that setup.

[@bentullett6068]

It was definitely a option on these. Rare to see now.

[@macgvrs]

Here is a thought. Sometimes it is possible to get replacement sections of the exhaust. All you have to do then is cut off the muffler and install the replacement. It is worth checking into. My Toyota had an all in one exhaust that I was able to replace piecemeal.

[@mancavehobbies6213]

Poor Tim he saw you coming Ian tried to leg it but you cornered him . Hope you're paying him well 🤣🤣🤣🤣

[@erik_dk842]

With the number of cars in disrepair that you own, some kind of lift or permanent ramps, that you can get under, if not standing, then sitting on a low chair, would sure come in handy

[@MattBrownbill]

That is a common place for silencers to rust through, I have welded countless ones up, to squeeze some more life out of them, even ones that have come off completely. Just add a bit of reinforcement, to stop the new weld eventually cracking.

[@barryphillips7327]

Overall Ian the exhaust does not look too bad, should be repairable in the meantime!

[@delukxy]

Drill a hole under the rear of the back box or boxes to let the condensation out. Not too small and use stubby self tappers in the holes if your MOT man is likely to get shirty. That sort of split is quite common, especially as you say that box has had a clout or two.

[@robames1293]

I used to do the same with holes at front and back next to the seam at the lowest point (found by dribbling water down the outside and letting it drip) but found that tiny holes did the job as the exhaust pressure when running would force the water out, shown by a stain around the holes.

[@pauldavies6037]

A good idea

[@Leon-uj7pc]

You don't have to replace the whole exhaust due a bad silencer( we call them mufflers), you just cut the old muffler off and replace it with a new aftermarket muffler. All you do is cut the muffler off right where the pipe goes into it. Then you get an aftermarket muffler with a larger inlet and stick the existing exhaust pipe in the new muffler's inlet and weld it up (or you can sleeve it and clamp it). There is no need to replace the whole exhaust for the muffler. Besides that exhaust looks pretty good. There is no rust or rot on the piping at all. This probably is a 30 min job at a custom exhaust place.

[@jimmyquinn9639]

Lovely job good old Tim 🚗🚙🚘⭐️⭐️⭐️⭐️👍👍👍👍👍

[@TheAlien1974]

Had an almera that had a full exhaust from factory but replacement was in two half's it stuffed the same power issue as yours did and turned out to be the back box, all the wadding had come apart restricting the exhaust gasses

[@TheAlien1974]

Suffered

[@robames1293]

I drilled a VERY small hole at the front and rear of the muffler at the bottom to let condensation out (pressurised when running). I live in an area where we don't have annual inspections though. A long time ago at a impercunious time, my Spitfire muffler developed a rattle. The perforated longitudinal tube had rusted through and dropped. I managed to pop rivet it to the bottom of the muffler.

[@shepshepherd]

[@johnf5817]

Ordering a part before you know it's the problem is a bit Hubnut, Ian! In future, stick the car on the ramp, shove a large potato over the exhaust and feel for the location of the leak. If the potato blows off, the leak isnt serious enough to worry about!

[@StevensPaul]

You must be....... exhausted after all of that 😀. Glad it's sorted 👍.

[@martinwood9014]

[@Pyjamarama11]

Well done to the designers who thought up a monolithic exhaust system that can't be broken down into more than two parts Genius

[@philtowle4683]

It's cheap. I once picked up an exhaust for a mk1 fiesta. It was nearly as long as the car as the exhaust manifold is on the front of the engine and the tail pipe sticks out the back. They brought one out and said do you want a 1 or 3 year warranty. I said which exhaust is the one you are showing me. He said its the same exhaust you just pay extra for the warranty. I paid for 1 year assuming they probably last longer if you can have 3 years warranty on the same exhaust.

[@micheltebraake7915]

That's a known place on an exhaust to crack, I've welded a lot in my car mechanic days, the exhaust will last for years again Ian.

[@MrFlyingguy]

Thanks

[@HubNut]

Thank you!

[@mbak7801]

Welding exhausts is normally an exercise in futility as it is very easy to blow more holes in thin rusty metal. It does look a bit like a manufacturing fault if there was enough metal left to make a good weld.

[@ThreeCoos]

Good job, thanks Tim 👍

I continue to be taken by how great looking Miss Daisy is. Between the color and the styling,she is most beautiful. I wonder if she has an issue or its just the suto trans. I say this because Im considering a Mitsu Mirage 1.2 cvt and it does ok but is afraid of hills.

[@jamescoe764]

Ian, it's your shambolic vehicles that make the channel 😊

[@workonesabs]

It seems that Diesel engines don't kill exhausts off as much as petrol. My Vectra still had it's original exhaust system on when the car was scrapped at 185,000 miles and 16 years later, but when I had petrol cars, the exhausts only lasted 3 or so years before they rotted. The 1.8 petrol vectra exhaust only lasted 4 years and was corroded to nothing, whereas the diesel was still 90 % ok.

[@neilb6029]

Diesel engines tend to deposit soot on the inside of the exhaust which ends up being a protective barrier from corrosion. This means they last much longer.

[@chrisrand5185]

I sold my 21 year old Jaguar XK8 last year after 12 years of ownership. It was still on its original exhaust, despite it being petrol. I think it helped that I rarely used it for short journeys.

[@ianfrost3529]

I had a car years ago when the baffles dropped it really dropped the performance of the car. It seemed that it was flowing fine but it wasn’t. New exhaust it was fine. I am surprised you can’t just get repair sections of the exhaust but I guess it’s because it isn’t a popular model anymore You could always become an hooligan and just put a straight through pipe in😁. Only kidding great video as normal.

Nah, don't need to go full exhaust, just get the sections necessary and one of them flanging tools that stretches the metal to make it a slip-on & clamp-it (maybe 'zorst paste too) fit, just have to remember the flange goes onto the forward-facing end of any pipework to make sure it flows nice... :)

[@robertmackenzie5850]

3:33 maybe the engine is coked up with the amount of short journeys it’s done in its life Someone else has also mentioned the silencer being blocked I tend to agree

[@jameswelsh5672]

Another gem of a video Ian. What cars are you taking to the NEC show in March?

[@HubNut]

Not sure at the moment. Probably only one.

[@jaggass]

Surprised that there isn't a lead gasket and spring bolts between the centre and backbox flanges which allows it to flex. When that failed on my Corolla it rotted out the centre pipe flange and many garages wanted to change the entire exhaust but got an aftermarket centre pipe welded on instead.

Haven't seen anything to suggest that - the exhaust attached to the manifold/cat and I did have a look for leaking internals.
