Ticking noise, exhaust leak or something else?

Sup guys,

So last Saturday night I flash tuned my car and went out to do some spirited driving. On my way home i stopped by taco bell and noticed a ticking noise in the drive-thru. I immediately became concerned thinking the sound was coming from my engine. I then got back home to thoroughly listen to where the sound was coming from. I opened the hood to listen for any odd noises and there weren't any aside from the normal cams and injetors ticking.

As I was still concerned about the engine, I checked the oil level and color, oil pressure, oil temp, cylinder head temperature, coolant level, all which appeared to be completely normal. Upon further listening to the sound, the ticking seems to be at its loudest from underneath the car.

Ultimately my question is, is it an exhaust leak or is there really something wrong with my engine? Just so guys know I have a UPR O/R xpipe I installed 2yrs ago and reused the factory header to cat gaskets (Not sure if the matters or not) I'll link a video below of the ticking sound.

I'm no expert, but I didn't hear anything that sounded critical.

Lol well that makes me feel a little bit better. Gonna change my oil in a couple weeks, while I have the car on jack stands I'm gonna blow air through the exhaust and spray soapy water around the exhaust flanges.

I've owned two Coyotes that ticked, I showed them no mercy and had zero issues.

Dang no mercy huh? Haha! I've own the car for over 3yrs and I find it strange I've never noticed the ticking until a week ago. I will say the ticking sounds more like it's coming from the passenger side, part of me wants to believe it could be an exhaust leak. I also do feel relieved that you guys don't think it's anything serious though.

Mine's started after about 3.5 years. No mercy here either. Always synthetic 5W-50. Catch can on passenger's side. I can't tell if it's an exhaust leak or "the tick." 37,600 miles. Tuned since around 4K miles. LT headers since about 20k miles. I think it might be one of my high flow cats ticking, or header gasket, to be honest.

I used to get the tick after each oil change, but haven;t had it since I went FI, which I find odd. The only thing I can think of is the FI tune bumped the idle up to 750 RPM.

I have the ticking after oil changes for a while and it eventually goes away, until the next oil change. I think there’s another thread somewhere about this ticking being related to a tensioner?

I found that thread I was referring to:
https://themustangsource.com/forums/...531664/index5/

Looks like Ford will only apply the TSB to 2011-2012s. Not sure why, seems like it’s affected ,13/‘14s for sure!

I think the guys above are pointing in the right direction. Mine ticked and Ford replaced the water pump under warranty which didn't affect the tick at all.

While I've yet to hear a detailed explanation as to the cause, I also haven't heard of it ever causing a problem. My Coyote is now over 35k, it has been tuned for 25k of those miles, sees redline at least once every time I drive it, no problems.
