Default Vibrations???

Ok I didn't notice this till yesterday but when I am in gear and stopped my car has a pretty bad pulsing vibration. I've had the full exhaust on the car for about 2 weeks now and haven't had any problems. BTW...it feels almost like something to do with the drivetrain...like the converter or something.
Now I did put up a post about how my car had a small vibration at certain speeds like 48 to 50 mph and when I would be in park sitting still it and reved it to about 2k and let it come back down a weird vibration came in and back out around 1500k. Does anybody else with an auto have these same symptoms. The new vibration while sitting in drive at a stop is driving me crazy. Any help would be great. Thanks.

Its probley the header hitting the kmember or just resting on it causing lots of vibration. The same thing happened to me, i loosened the drivers side header and then g rinded away a notch in the kmember. And the vibrations were completely gone. hope that helps

Checked to see if it was the headers resting on the k member and they don't. So any more ideas of what this vibration may be. It really feels like its coming from RIGHT underneath the center console.

Well just trace the exhuast back and look if its really close to the floorboards or anything. Also when you put your car in drive with the engine on the exhuast may move some causing it to hit something. so how much clearence was their between the header and the kmember?

A good bit of room. Like an inch or so. I put the car in drive and pulled up the ebrake and look at the headers and underneath the car and I don't see the exhaust hitting anywhere. But to better explain. It's not a constant vibration. Comes in and out and gets worse sometimes and then not so bad. It just started doing this a few days ago.

Theirs also a casting tab it could be hitting on the block, but probley not. it really sucks finding vibrations especially ones that are in and out. I guess just keep looking and try to find the point where its closes to the frame or floor boards.
