I have a 1992 325i sedan and my problem since i bought the car seems to be the exhaust system. The engine run's sweet as a nut and does not make any funny rattles or anything.
The annoying issue i've got is the fact that when you accelerate you can feel horrible vibrations through the accelerator relating to the revs and exhaust tone.
I have changed my muffler (for a genuine BMW) still the vibrations are there, i have changed my cat for another one, knowing to work. still the vibrations are there, really annoying, arround 1.5k to 2.5k you can feel them the worst.
Can it be my Manifold? or just a bad muffler (bought in august this year) or a bad cat? when the car is at idle you can feel the car shake and sputter but the revs remain solid , im utterly confused, oh yeah replaced the o2 sensor as well...
Please somebody must know what this might be. I used to have a 318 and it was considerably smoother than this car!
