Will i die in a ball of fire?

[dingg]

Just pretend it didn't happen, it'll eventually disintegrate

[Red9zero]

Put a mouse up the exhaust. It will chew away the rag and turn it into small pieces, which can then be hoovered out, along with the mouse.

A bit more extreme - remove the backbox, pour petrol in, light it, run away, let it burn out, shake the remaining ash out? (Might damage the baffles although you'd think that would all burn up through normal driving if it were that flammable.)

On the off chance you might get desperate enough to try this, bear in mind that it's likely to expode rather than burn.

Key bit highlighted.

There won't be chance to run away!

This is what'll happen, although the smiley is incorrectly named! :

I speak from experience......

Do you speak with no eyebrows?

dont understand the hoover bit, why not just run the engine and listen to where its leaking?
or does it involve something sexual???

Petrol is quite lively. I tried to clear the weeds off a bricked path with a cup of unleaded. Stood back a yard and chucked a match. Watched in surprise as the flame front shot past me by another metre. Fortunately denim is quite good in these situations, so no harm was done, especially to the weeds, but it nearly triggered my built-in sprinkler system.

Paraffin, diesel, kerosene, meths... all jolly good at livening up a fire. Can be chucked about with gay abandon without causing instant guaranteed death. Butane/propane - be careful. Petrol - be really careful.

This ^^^^.
A metre of hose, any old hose, one end to your ear, the other sweeping the exhaust system, starting with the likely area eg joints, welds and seams...

Young and naive, I once decided to turn the ignition off (a car before steering locks) and coast down the big hill into Otley. Put it in gear further down for some engine braking. Turned the ignition back on near the bottom to be greeted by the huge explosion. The exhaust system and silencer were completely ripped apart.

Igniting neat petrol in a silencer is not to be recommended!

always makes me laugh on films when you see people chucking a cigarette in petrol for it to blow up, no it doesnt, it goes out. needs a flame to ignite it.

I'm just waiting for pictorial evidence, then it may qualify for legendary status along side the how to dispose of a garden shed thread.

I’m in the sexual experiment gone wrong conspiracy club. OP post up an X-ray of the rag /coke bottle and we might be able to advise you of the next course of action to take to extricate the misplaced article.

I used to do this for fun. Never blew an exhaust system up though, just made a lot of noise.

And if that fails, put a cat up the exhaust to get the mouse....

[Caddyshack]

I would just run it and wait for it to break up, pretty sure the exhaust is fireproof.

used to flick the kill switch while on full throttle on bikes, gives an impressive bang, yes i was a tt, never blew up an exhaust tho.

[White-Noise]

Haha this is am interesting one.

I've not done this but I did have a somewhat failing back box on my mr2 many years ago. It was a single exit blitz. The first time it must have partially blocked the exhaust as it just felt like you were towing a caravan. I had it cut open and cleared out as I had no idea what was wrong but it wouldn't rev freely and felt heavy.

Some time later the other back box (it was 2 in a row we suspect added by a previous owner in japan) actually blew out on the m40 it looked like a bird had been shot.

I would think you could risk the Italian tune up route and it may well work but if it was me I would be taking it to a garage. Boring sorry!

Nonetheless if its a twin exit not much risk in starting it up and having a tease though??

[E-bmw]

I can't help you, I'm afraid, but I will say whoever told you to do this should be ignored from here-on-in!

It would have been very simple to just listen, or at worst put your hand over one or the other to help diagnose the site of the issue.

If you run the engine the exhaust gets hot... really finger-burning hot, within about a minute - nowhere near enough time to run your hands along all the joints and connectors looking for a small leak.
The vacuum just draws air in (you could set it blow if the hoover has that option) and you can put your hands all around the still-cold exhaust and feel/listen for a change in pitch that indicates a small leak. Much less painful

As you can clearly see, the rag has completely disappeared inside and is not at all visible.
Any Saab experts out there will notice that the silencer is hanging approximately 1.34mm lower than standard, which is due to the extra weight of the rag.
