weird vibration coming from passenger side area when at 2000-2200 RPM

[ExplodingCubes]

Hey guys, first time post, correct me if I did anything wrong

I just turned 18 and I know nothing about repairing my 80 series, it's got around 340k miles, and it's making a strange vibrating coming somewhere from the front end on the passenger side. I've done some research on this website and I can't find anything, some similar threads said sparkplugs, but from my understanding that is most noticeable when the engine is at lower rpm, on other car forums, people have said engine mounts, but those look fine on my car, one thing that could be the issue is that the exhaust could have something wrong with it. The only work I have done on it recently is replacing the alternator.

Any help would be appreciated

here is the video for you all! I got it fixed and thank you very much for the help!

So, what did you fix?

So, what did you fix?

just took off those heat shields on the exhaust, I need to find a place with clamps, and every single bolt broke with just a little force, so I need to find bolts as well.

Any clamp will do fine but stainless probably best. Glad resolved and don't forget pick up something for the lady today while at Home Depot!

So, what did you fix?

alright, drove it, worked fine until about 60-75 mph, now it's doing the same exact thing, which is strange, it did not vibrate whatsoever with the heat shields removed, and I guarantee that the shields are on correctly and tightly.

Edit: Also at the 2000-2200rpm mark, it's also slightly less aggressive.

I once had a hardened piece of dirt stuck between the cat and the heat shield that would vibrate at idle enough for me to notice.

found the leak, it is indeed and exhaust leak, just did not look far enough

i have come to the conclusion that every bolt that i try to take off will break

I believe the gasket you are looking for is on the end of that muffler pipe. Crush gasket iirc. I believe this is it. 90917-06072 Genuine Toyota Gasket, Exhaust Pipe - https://www.toyotapartsdeal.com/oem/toyota~gasket~exhaust~pipe~for~center~90917-06072.html

all fixed after two ish weeks, turns out when I was replacing the alternator I pulled out one of the wires for the spark plug, runs like new now

all I needed was to plug a wire in
