Wierd noise when I let off in high gear.
Only does it in 5th and 4th, almost like a rattling noise.
Can anyone help? Thanks.

I have noticed this in my car as well. I'm pretty sure it's just vibrations somewhere, but not worth spending countless hours locating it.
I've come to realize a few years ago that when you mess with cars you become very paranoid to the slightest of noises lol

hmm I just watched your video though and that sounds a little worse than unworthy engine vibrations.
does it occur with engine speed or vehicle speed?
I'd go through and check your wheel bearings, ball joints, and tie rod ends just to eliminate that or find a possible cause.

OP, the rattle you hear is not all that uncommon in Evo's. In most cars that have this issue, you also hear a slight rattling noise when the car is parked & idling...that noise gets louder if you turn on the AC compressor. If you press the clutch pedal in though when it's parked & idling, that noise immediately goes away. On the freeway like you describe (45mph-ish+ in 4th/5th, the noise is ONLY brought on by releasing the throttle - steady cruising/accelerating has no abnormal noises).
Here's the thing - in 8 years of trying to track the source of this problem I've come up mostly dry for the most part. There are COUNTLESS threads on here where members ask this same question. The closest I think I've come to finding the most logical answer is that the source of this problem lies with the clutch release bearing as the producer of this rattling noise. Most likely, the cars that produce this noise are ones where the clutch fork is not positioning the release bearing correctly either due to a poor quality control of the clutch fork (most likely), the bell housing where the fork itself attaches (less likely), or lastly, possibly the slave cylinder (less likely). My money would be on the clutch fork.
I'm not claiming that this is 100% the reason why your car makes this noise, but in my years of searching for the answer has brought me to believe the problem lies here..

I have been trying to track down a very similar noise. The noise is only during declaration while in gear, any gear. The slightest throttle input, or pressing the clutch pedal makes the noise stop. I have an aftermarket clutch, but the noise didn't start until months after the clutch instal. I had the t-case rebuilt, and it had no affect on the noise. I have gone over the car many many times looking for anything that could be vibrating against something else, but everything seems tight, and the exhaust has a good amount of clearance all around it. After some research, and talking to a trans shop, I believe its the transmission input shaft bearing, maybe?
