yes I agree some people complain to much as well, but I have to tell you if you was in my car you would say HOLLLY @@%%!!!! And also there are some people who are asking advice< not complaining, I thought that was what this forum was for. But now I also thought of this. I had my exhaust welded soild to my headers because the clamps they give you are not very good. And it hit me last night, my trany would be lower with the poly mount, so would that put the engine and exhaust in a little bind and make the vibration worse?? I don't know why it is so bad but I would never drive my car like that and I know for a fact if you knew what I was talking about you would not either. I would have a rattle bucket after 6 months..LOL Maybe I will try the driveline spin and check it out again. Thanks again for the positive info.
