Default Slight vibration at 4300-4500RPMS

Think it's from the exhaust. It's not a rattle, it's vibration. It could very well be normal and I'm just noticing it now. Car seems to get loud at that RPM. Anyone else notice this? Notice I can feel it in the shifter a little bit too. Car is stock
Thanks

Same here. I think it's normal. Especially in 1st gear.

The car DOES get louder there. However, I get no vibrations or anything, just a really sweet exhaust note when under normal accel. at that rpm range.

Thanks guys. I'm thinking it may be the exhaust resonance. Hmm

yea i think it is normal.. i don't notice a vibration when i am accelerating but once in awhile i notice a vibration when the tach is going back down. i am pretty sure it is around that same rpm.

kinda on the same note does anybody nootice a rattling noise when the clutch is depressed rapidly at a high rpm in first?i am pretty sure it is just the clutch engaging at a high rpms, if i push it in slowly it doesn't do it.
