Hi,

I recently did a long journey in the car R50 Cooper and when I got home I found there was a cluster of long silver grey hairs/fibres coming out of the car’s exhaust, it looked like a wig.
I have been told that these are fibres from the rear box? Or muffler? Are they the same thing?
How urgent is it to get this sorted.
One garage wanted £160 for a new back box and £60 for the work. A Mini parts place in Kent had a whole first gen exhaust for £20 in good condition but that’s a bit tricky to get.
Is it a bad idea to do any long journeys until I get this sorted? Or will it just get louder as more fibres break away from the rear box?
What am I looking at here?
Thanks
T

Sounds like the packing in the rear box is breaking down and blowing out. All that will happen is it will get louder. I'd shop around for an exhaust but wouldn't even ask the likes of Kwik fit or National Tyres they are way to expensive. I've changed lots of exhausts but never a mini they aren't hard but as said above the higher you can get the car the easier it is.

There are two mufflers in your exhaust, the back box and one behind the cat. I believe the wadding could be from either of them. The back box will definitely have it in but i'm not sure about the forward one. Some cars only have baffles (no wadding) in exhaust boxes so close to the cat'. Either way I would be replacing the whole system from the back of the cat'. It's only a small system so won't cost much. I do all jobs on all of my vehicles (servicing to engine rebuilds) but even I don't bother with exhausts as they're a faff without a ramp and so cheap to have fitted that you don't save enough money to justify the effort.

Thanks for that

So is it best to just take the hit at an exhaust centre, or buy the exhaust and pay an MOT garage to fit it?

I would never go to an exhaust centre they over charge as mainly fleet companies use them, try a local independent garage, 9 times out of 10 they are cheaper, recently had a price for a little peugoet the price difference on an exhaust was in the hundreds.

In true 'internet style' my experience is the exact opposite :D. I've used exhaust centres on the rare occasions that I've needed to replace them. No matter though, it's free to get a quote so would suggest you try both and I'd be interested to hear how you got on. Systems of the size you get on a mini I'd expect to be in the £150ish range (fitted).

Edit: forgot to answer the 2nd half. Generally garages don't like people bringing in their own parts so I'd just ask for a quote to replace.

Just took the car to Kwik Fit and they quoted £235 with fitting, I only paid £600 for the car, but they did say a lot of the after market parts on the internet are badly built, but I guess they would say that. This might be a case of cough up and get it done, time vs money etc.
