WTF? Muffler blew off

So I was driving late at night and pushing the car a bit, doing the recommended weekly redlining. On one of my redlining stints, around 6k rpm in 3rd, the exhaust note suddenly got a lot louder and stayed louder. The backfiring also became a lot more pronounced and I suspected that I got a hole in my muffler some how. When I got home, I noticed my passenger side muffler was askew so I looked underneath and the entire muffler had actually blown off. The pipe at the front end of the muffler is bent to **** and I think the muffler is only hanging on by the hangars. WTF? Has this happened to anyone else?

i went thru about 5 cheap mufflers like that with my old NA. It ran pig rich and loaded the muffler up with fumes and backfired at redline. i never quite figured it out so i put a glass pack on it and a pair of cheap APC cans on it

This is what happens when you combine a rust (or cheap) muffler and backfiring...
Yes, it can do damage to the exhaust system like this.
This is why I dunno why idiots WANT to cause the exhaust to backfire...
*sigh*

ya, the only time ive ever heard of that is with older mufflers that rust out and disconect from the pipe... that sucks though man sorry, just grab some wood glue and throw it back on there... thats what my friend did with his hyundai accent, but then again let this be a lesson to all of you to never first off own a hyundai accent, and second off at least dont moddify it

It happens. I've never seen it on a 2nd gen, only heard of it. However I blew up a muffler in my SA due to stuck carb secondaries and that wonderful (no sarcasm) thermal reactor exhaust.

Take a pic of the muffler for us. The same thing happened on my saturn, blew the back end of the muffler clean off the engine side. Pretty wild.

that is it. most of the exhaust problems that you will have are from running rich and cheap parts. i had a friend blow out a cat from running too rich.

my buddy had a dump truck with a big block chevy engine. We were having a bunch of trouble getting it started (flooding the crap out of it) and when it did it blew the muffler up like it was a bomb. It had a whole new exhaust system in it, just comes down to the fact then when fuel collects in your exhaust and it ignites, well it blows up.

For all you people who assume I was running a cheap muffler, no, it was stock. Why do you assume I cheaped out and put on some piece of **** Ractive mufflers or something?

Deep breaths man!

People are just trying to put some ideas out there, be thankful they replied.

They don't know you don't have a crap muffler on there so they put the idea out there.

Anyway, it sounds like you are either running rich or the thing was pretty flooded recently.
