Exhaust Leak or Valvetrain Noise??

[Ghost2013SCC]

I’m new to headers so don’t bash me too much. I just installed shorty headers on my 2013 Sport Crew Cab 5.7L. On a cold start I get the tick noise. After it warms up the tick is gone. I get the tick during acceleration. It get faster as speed increases but goes away under cruising. Also, the tick isn’t noticeable at RMP range of 2500+. I attached a video but you can’t really hear the tick due to the exhaust.

What do you guys think, exhaust leak or valvetrain noise?

If it ticks at idle when full temp you may have reason for concern

100% sounds like a exhaust leak maybe you used wrong gaskets? or did not tighten them enough or possibly over tightened the 2 main bolts for the flange have seen it happen alot it ovals out the joint and wont seal.

Headers amplify valvetrain noise.

Yeah headers are thinner than the ol stock minifolds, give you a lot more noise.

I’m having a similar issue with my afe headers, entirely my own fault.

my issue was mainly a crack but I also have leaking at the collector sockets.

I ended up using Permatex muffler sealer.

Imo that does sound like a leak. The tick while louder with headers shouldn’t be that noticeable especially with an exhaust.

Did you end up figuring out what it was? I'm having the same issues after I installed shorty headers
