N14 Ticking Sound

Hello everyone,

I have a 1996 N14 with approx. 1.2m miles and yesterday during my drive I heard this weird sound coming from exhaust area of the engine. It goes up and down with acceleration and deceleration. My MPG is not affected and truck doesn’t run weird or any different. I do smell more exhaust than usual. I’ll post the video and tell me what you guys thing. I’m just confused as to what it could be. It sounds like an exhaust leak. If anyone can help identify this sound before I go ahead and take it somewhere. I just want to try and see if it’s something simple. Thanks to everyone and I appreciate any input or direction. Video below:

 

If it helps, I don’t have any oil pressure issues. Still idling at 10 psi and 32 psi at highway speeds.

 

Hello,

Yes, it sat literally about 10 hours and I fire it up to make sure it still turned over and it started right up no issues as far as starting. I’m just stumped. All that noise can be a bad manifold joint? Seems too noisy but I can be wrong.
