my car is loud...and NO its not the muffler?

Question

i backed into a snow bank a few days ago and later that night when i got into my car to leave it sounded realllly loud. i know what it sounds like to have a hole in my muffler but it was a different noise. When i accelerate it gets really loud and i can hear each shift (its a 2000 automatic Camry). I had my dad look at it but from the outside it sounds normal! even when im accelerating. but when u sit in the car w/the door shut its loud. there is no hole, dent or anything else in the muffler...

does any one have ANY suggestions?

Answer 1

Take your car to a exhaust specialist shop. Since you backed into a snow bank (you don't say how fast or hard the bank was) I bet you a fat man that you dislodged a gasket, connection at the converter,muffler or engine exhaust.

Being inside the car the sound would be magnified if it is near the engine or under your seat area. Whereas while outside the sound, even small opening, would not be confined and spread out more.
I am curious what you find, so I hope you EM or IM me and let me know.

Answer 2

that bank of snow, could have stressed a connection, causing a crack that needs to be welded. get it up on a lift, start the engine, and carefully check every thing from the muffler, all the way to the engines exhaust manifolds. ignore nothing in your inspection process.

a seem on the mufflers construction, may have let go, and you won't know it, till you feel hot gasses comming out around it.

Answer 3

call the vehicle areas shops and ask for a inventory muffler. i exploit a inventory Walker sort for the quietest sound. make valuable in spite of you get, are not getting a rapid muffler. those are no longer quiet.

Answer 4

The sound might be coming from under the hood (the manifold)
it could have pushed it off, happened to me b4 heres an idea of what it might look like on a camry but not sure never look under the hood of a camry http://www.1aauto.com/1A/ExhaustManifolds/Toyota/Camry

Take Care

Answer 5

So my Toyota Corolla started making a loud noise once; it was something called the "donut gasket"? It is what attaches the muffle pipe to the engine, or something like that.
Just a suggestion...

Answer 6

Some cars have heat exchange ports in the exhast manifold that could be leaking or the manfold gasket itself may be bad or the manifold could be cracked or broken.

Answer 7

maybe your exhaust manifold was damaged. That can create a louder sound than what you are used to, but isn't the muffler, per se.

Answer 8

yea i would check the donut gasket , maybe the muffler got jerked and broke the gasket, makeing a put put put sound or spittering sound
