So i have a cat back...
And when i got it it sounded great.. it was loud but tolerable.. great tone.
Then this happened...

Now think of the pretty purple is flaming hot red... and say to yourself how much my camera phone sucks.
After this happened and i got it all fixed and running right again, a few things have changed..
It melted my gaskets to a fine powdery crisp.. it raped my nice new cat i recently bought to pass smog.. to be more precise it deformed the screen closest to the rear of the car, and turned it sideways so its free to rattle its little heart out.

So i picked up some new gaskets.
I removed the remnants of the dislodged screen inside the cat and left the front one there since it has no problems.
Then i reinstalled the cat back.
When i started the car it was at first pretty pleased since the massive leak from the flanges was fixed and my car didn't sound like a wet paper bag anymore.
but then it settled down to idle and started rattling.. like a loose screw noise. so i checked it out and came to the conclusion that its inside the muffler. so i drove around and the sound is like 70% louder then before. and rattles!
I am assuming that a piece of the cat fell into the baffling and is stuck..

So my question is would overheating and shooting raw gas and flames out my exhaust melt the packing in the muffler and cause a large sound increase?
and would buying a new muffler of the same type and welding it on fix this.. or would not replacing the resonator mid pipe at the same make it kind of pointless...

any input is helpful, i searched and didn't find anything quite like this...

Are you running so extremely lean that you exhaust starts to melt?? is that even possible?

Give us more details on the motor, if you can cut the muffler open or what is rattling remove what is rattling and weld what you cut out back on... but you are running extremely lean, i have only seen this once on a late 90's ford econoline van lol, and it was just the cat was glowing orange not the whole damn exhaust...

This was caused by a extremely leaking injector on cly1 and mixed up plus wires on 1 and 2.

Its fixed now and the car runs 100% normal.
The question was about the muffler not the motor :)
And its just a ka :D
So...
Would burning the hell out of my muffler make it louder...
And would welding a new meagan muffler of the same size and type be worth it..


i guess i could cut it open and look.. but then i wouldn't have a muffler until i replaced it

More than likely you burned up all the steel wool in the canister and now that cylinder with the holes is rattling around or the steel wool turned in to a block of metal and yes your mufflers probably gonna be louder now
