Rattle under acceleration after 1500rpm

[smokey_the_xterra]

I hear this rattle noise from under my Xterra between 1600 and 3000rpms, super weird, I can’t find a loose shield on the exhaust, I thought it was u joints so I spent a few hours replacing them and the noise is still here! Maybe I’m skipping something on the exhaust? I had a shop say it’s trans but it’s shifting fine with no slips. Here’s a sound clip

2005 Xterra heat shield rattle??? What is it? Between 2k-2400rpm

I have the same thing and I hate it. I’ve clamped down every heat shield, and even crammed rubber wedges in the cat shields to rule them out. I have a strong suspicion it’s the VIAS actuator valve (https://www.z1offroad.com/intake-ma...finder-vias-power-valve-actuator-p-23333.html) but haven’t yet confirmed.

There are lots of threads on other sites talking about it as well as YouTube videos. (Search VIAS rattle Nissan)

That would be nice if it’s that VIAS thing lol, I’ll make sure it’s not my shields and then mess with that, I just hate tossing parts at it and then it’s not the problem lol.
