Hi everyone. I have a gurgling sound when I start my LC and under acceleration. I changed the exhaust manifold gasket, downpipe gaskets ( to manifold and cats. It is still making the gurgling sound. You guys have any ideas what it might be?

I've post a video. Im not sure if you'll be able to hear it
sounds like an exhaust leak, could be a crack on a weld around the exhaust flanges or at the y pipe if you have a 95-97

I'll take a closer look. From underneath it sounds its coming from the driver's side, but the noise might be resonating or something. Thanks I'll keep you guys updated

That's an exhaust leak. It appears you have a 93-94. You have split cats on the right (PS) of the truck.
When the truck is COLD, start it, then run your hand around all the flanged joints on the exhaust and near the manifold joints and feel for puffs of air.
Also look at your O2 sensors, as these are know to have the nuts rust and fall off, then the sensor falls out of the hole.

I checked where the downpipes and manifolds meet....and you're right its leaking there. I just replaced those gaskets. Any tips in making it a tight seal?
New hardware and Toyota gaskets (the ones from Walker, Magnaflow, etc fail on short order)
Tighten evenly across them. Do one side then the other and alternate to keep them evenly torqued when tightening.
