Change your spark plugs. A poor running engine can do terrible things to the inside of your muffler.

If you live near, on or continuously drive on uneven terrain then you might be scraping somewhere over time creating a hole or improper installation.

When i accelerate it sounds like a hole in my muffler, but when I maintain a constant speed it goes away, what can it be?


It could be a small hole or the baffles are loose in the muffler itself.You can either check this out yourself by jacking the vehicle up and starting it and see where the noise is coming from or have it looked at at a repair shop.Make sure they show you the problem if they find one.Don`t just take they`er word.Hope this helps.Good luck.

Every time i put a new muffler on my 1997 jeep grand cherokee the motor bakfires and blows the muffler compleatly apart it dosent do it right away it runs fine for a few miles then boom then it starts to...


What a funny set of events.Of course the tail pipe is clear(you would have checked that)The only other thing it might be is the cat/converter is blocked.New muffler is allowing a heap of air through and it suddenly clears and the bang.They do block up so it may be worth getting it checked.Hope this helps

My exhaust is very loud on my 316i bmw. all looks new and i have paper work to prove this. not a sport exhaust either. how do i quieten it down or is it blowing massively?


Seems to me that you may have a bad muffler, a hole has manifested where rust may have collected over the years, or a broken flange.
Either way, your local muffler shop (Midas, Etc) should be able to remedy the situation quite easily.

Hope this helps,

96 grande cherokee back fires and blows hole in muffler,the muffler is bulked up in center.did the cat converter cause this or did the muffler stop up from lack of air flow .


Sounds like you have a ignition timing issue or it is possible your engine is running extremely rich and a partially plugged muffler and after the fuel vapors accumulate in the exhaust system then you get an explosion causing your muffler to expand. However I would first look at ignition timing and if that checks out move on to exhaust system or emissions systems.

Loud muffler noise up front of vehical.what is


If the noise sounds like your muffler, but isn't coming from the area of your muffler, then you have an exhaust leak upstream from the muffler.

From the front of your muffler, follow the tubing forward to the catalytic converter, then forward to the engine exhaust manifold.

If you start with the car sitting for a few hours to make sure it's cold, you can use your hand to feel for blowing leaks while the engine is running, but chances are you'll be able to hear it. be careful of the catalytic converter itself, as it heats up fast, so check that first.

Once you've found the leak, the fix depends on the emissions laws in your state. If you have none, and the leak is in the middle of the pipe, you can buy pipe patchers (metal preferred) through auto parts stores or catalogs/websites. If you have strict emissions laws, or the leak is at the junction of the catalytic converter and pipe, you'll need to replace the failing part.

Muffler is loud and rattles due to debris and possible hole


either live with it or get out a saw and cut it out and weld in a new exhaust muffler. or you might get the measurements and get one to fit where you cut out the old one from your parts store.. make sure you measure your pipe and get a muffler that will fit over the pipe .. You will need clamps for the muffler also.. thanks and holler if you need more Jerry
