My 100hp has failed it's MOT on 'front exhaust has a major leak of exhaust gases flexi (7.1.2)'. Initially the garage thought that this would be quite a cheap part but have since said the only part available would have to be the whole exhaust due to the chrome tip on the 100hp. This means a £250 bill.

Is this right or can the flexi front part of the exhaust be picked up and fitted separately whilst retaining the existing other parts of the exhaust?

If not, I'm thinking a different exhaust might be a better option still, perhaps giving a better exhaust note, but would these be much more than the standard one at £250....

Any help would be much appreciated.
 
I don't have a 100bhp Panda but the flex failed on my GP, I measured the pipe for diameter and length(of the flex) and good 'ol EBay supplied the parts. Tool requirement was a hack saw and a spanner for the clamps. 30min job, easy and cheap <>£20.00
 
The exhaust is in three parts.
Manifold, includes the cat.
Centre or mid section, includes flexi.
Rear silencer.

So the centre section, with flexi is available on it's own and isn't too expensive.

Trouble starts when attempting to split the rear silencer from the mid pipe, they rust and seize together and more often than not requires the rear silencer to be peeled from the mid pipe at their joint, ruining any chance of reusing it.

So I'd say your garage wants to swap both the mid and rear sections due to this.

You could try a new stainless system, https://www.longlife.co.uk/
If you plan on keeping it any length of time, it could be worth it, generally a genuine system with last around 5 or 6 years and a pattern one, 3 to 4 years.

As said above. A replacement flexi can be sourced and spliced in.

I've booked my 1.2 in with a Longlife Agent for a replacement system, from the cat back, so centre and tail section. £330 made to fit, fitted and guaranteed for life. Worth a quote for the 100hp.

Strangely, on mine, the joint between centre and rear sections has no clamp. Looks like it fell off a long time ago. But the two pipes are so rusted together that there is no leak. Has passed 7 MOTs like this. Separating them would certainly render both bits scrap.

Thanks, I've messaged longlife for a quote

Ok, thanks. I'm getting an idea now of why my garage have said they have to replace more than the flexi part.
 
A lot of us replace the mid section with a straight through pipe which should last longer and is about £90 but does make the exhaust louder which is not to everyone's taste.

I don't mind going louder :), do you have a link to a recommended one?

Think you need to inspect the rest. Changing just the flexi would be the way I would go if the rest is sound. But no point if the rest is being held together by rust.

Managed to take a look underneath myself at the garage today. Although it was the flexi part which failed the MOT, and i could see where it is loose and blowing from, the rear section is pretty rusted overall and looks rusted onto the mid section. There was no clamp here either.

I suppose nearly 10 years and 66k is not so bad out of an original exhaust, looks like a full replacement is required.

Always better to see for yourself.



10 years is brilliant. Wish pattern parts lasted that long.

Mine's just over 11 years old, just passed an MOT, but looking like it won't pass the next one. Having a stainless system early next month.

Petrol exhausts last a lot longer these days. The killer has always been internal condensation, as water is a product of combustion. Catalysts add heat to the exhaust, so even on short runs the exhaust retains very little moisture after the engine is stopped.
Sadly this is killing the aftermarket exhaust manufacturers. My local garage that did the MOT said it is difficult to source good quality aftermarket exhausts. Apparently the return on sales does not justify proper investment any more.

My stainless system should be only slightly more than an OE mild steel one. Should outlast the car, and me!

Hence why my exhaust parts are now sourced from Italy and Poland.
