When I am sitting there with my foot on the brake and I have the car in either R, D, S, or 2... the car vibrates a lot. I hear a lot of vibration coming from the back of the car and the mechanic told me that it might be related to my aftermarket exhaust. I have a greddy exhaust and it is toching the chasis. could this be it, if so what can I do to avoid the vibration?
the timing belt was changed 10k miles ago, so I do not believe that it would be that.

I believe you said it right there. I'd put my money on that....unless you can describe the vibration in more detail.

how would I go about fixing the problem if it is the exhaust? should i just stick something btwn the exhaust and the chasis? what material should I put there?

 

At the moment, I can think of a few things:

1) Get different rubber pieces for the hangars. They come in different sizes, and maybe you can get one that puts more distance betwen the pipe/canister and the chassis.
2) Go to a muffler shop and have them reweld the hangar. It should only be a small fee and shouldn't take long at all.
3) To to a local auto store and look in the muffler/pipe aisle. There should be things you can buy to reposition the pipe just a little.

 

temporarily space the exhaust away from the body and see if it still vibrates. if it does then its probably your motor mounts

 

You didn't mention anything about the exhaust noise.
No clanking sound ?
I agree with earlier post saying engine mounts going south.

 

there is no clanking sound... its just vibration all over the car, its a constand vibration and once I start driving (stepping on the gas) or even if im just coasting in gear, it wont do it anymore. The only actual noise is a rattling noise coming from the back which is probably I am not sure what it is because everything is securely placed and the license plate is also securely placed.

 

It's your exhaust. It's definatley time to get longer hangars. I need some too while you're at it, can you pick me some up?

Fix it soon before you have a hole in your nice aftermarket exhaust.

 

whoa, what do you mean i will have a hole in it? I do not know much about cars at all... i am guessing that hangars are what hold up the exhaust, and im guessing that I need longer ones so that it doesnt touch the chasis, but I do not understand how this could turn into a hole in my exhaust.
I tried putting a peice of high density foam rubber and it cut down on the rattling and vibration in the back, but the car still vibrates a little overall, a lot less than before, I also notice that in R it does it less than in the forward gears.
