Ok so the bottom of my car hit like a rock or the road or something i just know i hit a huge pothole and bottomed out. Right after it happened the car started acting funny, its about 2-3 times louder, the inside the car vibrates pretty bad espicially under the driverseat. when i put it into first gear and start engaging the clutch it is VERY rough, it still drives and performs the same but acts like its really f*cked up. I'm really upset right now and freaking out, because my car is my baby and im so low on cash, im thinking its something with the exhaust or something, maybe like puncture? i dont know, anyone know what it could maybe be? is it gonna be expensive to fix?
Please help, any input is appreciated.

Seems to be coming from the front vibration is worst under drivers seat, brakes fine, steering fine car still performs ok, didnt see any structural damage but was at night with a flash light. No weird leakages...

Chances are the exhaust took a beating, and maybe the tranny. Get the car up on a lift and look to see if theres any shiny bits. Anything that made contact will be shinier than other stuff(I think).

Some one correct me if I am wrong... I am in my towel or else I would run out and look at my car for this... But isn't there an exhaust mount appox where he is talking about? If so, I would say that it has been knocked off or out of the mount... But I am having trouble remembering because it has been so long since I have been under my car.

1st of all, i do not believe there is an exhaust mount under the drivers seat. the exhaust mounts are:
exhaust manifold
right under the tranny
all the way around the muffler
and near the drive shaft center bearing

it is MOST likely ur exhaust.. jack it up and see
is ur rpm any different?
dont fret too much about it

also, do u have any lights that went on?

No lights went on, im just kinda upset, the car shakes real bad between the lower rpms and is pretty annoying, plus it just sounds pretty bad.

do you feel a loss of power?

dude, if no lights went on, that means u didnt do anything serious..

did u jack it up yet?

is the car shaking because of the vibrations from sound? when u rev the car up, without it being in gear, at low rpms, does it still shake?

Sounds like maybe you broke an engine or transmission mounting point or perhaps just a bolt at one of these points.

It could also be a driveshaft problem. Check the guibo (flexible connector) and the driveshaft itself for any dings or bends. Also look at the driveshaft and see if there's any shiny spots where small balancing counterweights could have been sheared off.

HTH,
Fred
