Whats the fibreglass coming out of my exhaust?

Question

and how much of my exhaust am i likely to have to replace? possible cost? Its a 1996 ford modeo

Answer 1

The fiberglass is most likely from the baffles on your muffler. There isn't really any other place in the exhaust system where fiberglass would be found. You may not have to replace any more than just the muffler which could run around $100 - $200. The exhaust from the Catalytic converters back could be about $500 - $600.

Answer 2

It's likely that the fiberglass you are seeing is the sound insulating material from inside the muffler. This is what makes the muffler work. It dampens the sound of the escaping exhaust gases. Did you notice if your car sounded louder? If so, then that would most definitely point to the muffler. As to the cost of replacing exhaust components, it depends on how much damage or wear exists. If it is only the muffler that needs to be replaced, a reputable muffler shop would normally charge between $150 - $200 USD.

I had same occurrence on my Rover. On the motorway, loss of power although having stopped to investigate car ticked over fine. Decided to drive on as could not find any fault. Few miles further a sudden "whoosh" from the rear and the car ran normally again. Once home an investigation showed strands of fibre hanging out of the exhaust tail pipe.
I decided that this was the sound deadening material from the rear silencer box and "using mechanical fingers" pulled out as much of it as I could. Obviously the material in the box had somehow collapsed and blocked the tail pipe stopping the free flow of exhaust gas and acting like an exhaust brake on commercial vehicles caused the loss of power. The "whoosh was it eventually blowing clear from the exhaust gas build up pressure.
I did not change the box and to date have suffered no ill effects and no increase in exhaust note other than a short bark if I accelerate hard and then lift of to change gear, sounds quite sporty.
My advice to you is check and remove any loose material in the tail pipe and rear silencer and if there is no obvious damage to the box and the car is not excessively noisy ignore it and drive happy.

Answer 4

Sounds like the packing in the muffler has blown out. You have a couple options...if the exhaust piping is still in good shape and does not have any serious rust on it, a simple cut and weld muffler from a muffler shop would do the trick. If your exhaust system is rusted out, a cat-back or rear section exhaust will be necessary.

Answer 5

Its probably the lagging from the back box and the back box will require renewing at a cost of around £40 to £50.

Answer 6

Its the soundproofing stuff from the exhaust box - probably just a new box needed, not a full exhaust. Fingers crossed!

Answer 7

No, no longer something to rigidity approximately, its in basic terms insulation cloth, your exhaust will in basic terms get louder. I had a V6 Granada and this occurred, my,my, what a marvelous noise! It appeared like a activities vehicle!

Answer 8

Its the wadding that should be in the silencers making a bid for freedom. If enough of it dislodges you will feel a lack of power. Don't know the cost, try Kwik Fit.

Answer 9

That would be the baffle in the converter That is what is in side , Have it checked out at the muffler shop not the dealer, hope this helps.

Answer 10

If there's anything solid coming from your exhaust, it's probably the catalytic converter. Get you wallet!!
