OK, just curious. Has any wrx owners noticed lots of engine movement when revving? I gutted my stock up-pipe a few months back, and my friend pointed out to me that whenever I revved it up, the engine moved like crazy. And it does. My motor mounts are tight, and I cannot figure out what else it would be. Any one else notice this?

 

It's pretty normal. Boxer engines are pretty unstable beasts. It's not smooth like a straight 4.
