um.. my muffler exploded...

well i was driving down the road at a constant 35 or so, just passing one of the few "thug" infested gas stations here when i heard a hell of an explosion and my damn truck moved...! honestly it sounded like a shotgun so i down shifted and hauled ass lmao. i stopped at a drive through a few blocks down and got out to check then i noticed my exuast was considerably louder, then a car full of ppl that were pulling out of the gas station i was passing got to the red light right by me and proceded to tell me that something underneth exploded, so i looked and seen this!

Click the image to open in full size.


now i suspect that running rich will cause something to this effect over a long term but i'm not rich, no black smoke or smoke of any kind, other then if i forget and pump it to start after it already warmed up then i get a very small puff of black then nothing. so wtf? i'm running no cat, pipe in the place and just what was the muff then out the drivers side behind the tire. any ideas?

oh and btw its a '86 yota truck 2.4l 2bbl

backpressure is about the only thing I know of to cause exhausts to explode... you know the old potato in the tailpipe trick, but even then your exhaust would have to be pretty well blocked to cause that kind of backpressure...

how long was the truck running I have alot of back fire when I first start the truck and it only back fires when I am decelerating.
I also do not have a cat and have thought about installing one if it would help stop the bangs that come out for the first mile from home every morning.
once my truck is warmed up it will not backfire.

I was just kidding.

On another note, I do belive the size is 2", but you might want to consider going 21/2" from the back out.

Replace the muff. then add an oversized chrome Meg to the tailpipe, and make sure it hangs out far enough to be seen.

It'll keep the "Thugs" at bay when you cruise down the avenue.

2" or 2 1/4" pipe.

I've heard of people getting too much unburnt gas into the muffler, and having that ignite. But I don't know if that's what caused your problems.

But that was their fault, sucking gas throw & igniting it just for fun.

I found this on another website. It's a reply to someone asking why their vehicle "back fires" so much.

Quote:
This is a very common misnomer in engine circles! What you are experiencing
is an after fire, not a back fire. A true back fire would have gases blowing
back through the induction system - NOT a good thing! I don't know why
the phenomena you are experiencing has become commonly known as a 'back'
fire, but there you go. I would guess that your weak inlet valve spring
is the most likely cause, as the engine must be drawing some fuel in when
coasting and this is no doubt collecting in the exhaust. To rule out exhaust
restriction try running it with the muffler removed and just a short length
of pipe in its place. The second most likely is a sticky exhaust valve when
hot. In more sophisticated engines there can be other causes for after
firing, such as incandescent carbon, late valve timing etc., but I think
your problem is much simpler.
After fire is the cause of a muffler explosion. Back fire blows your air filter up.

do you weld?? you mean cherry bomb glasspack right? if so give this a try. cut the glasspack in half (be careful not to breath the packing while cutting, it makes your ears ring and you get dizzy an your vision goes weird and- well i think you get the point), take out the packing and the tube down the center, and weld 'er back up. not sure if its 100% legal but it sounds so good you dont even need a stereo or you could just replace it with a straight pipe from pep-boys.

by the way i like your story, it made me laugh
