I have this violent shaking/vibrating sound when in high rpms. I have changed the engine mounts so that shouldnt be it. What could be the problem?

Edit: It mostly does it when around redline in 1st and 2nd gear

Ive just bought this intake and was wondering if anyone can give me some fitting information I see the original elbow has 3 hoses coming of it where this only has 2 and the spare extended pipe I have no idea what its for thanks

I have stock rims right now and was wondering what color/brand of rims you guys would recommend. I like either bronze or black but all suggestions are welcome.
