Hey guys,
I'm a newbie here - long time car/truck enthusiast and a master licensed Honda technician.
Mods please move this if it's not in the right area.
So I have a 2017 Ram 1500 5.7L with 65,00km's (40,000miles) with an exhaust noise that has me stumped - and I'm a licensed tech - LOL. I do not have any "hemi tick" on start up or a manifold leak, I've done my best to remove the heat shields off the manifolds and inspect all the bolts, and I cannot replicate the sound while revving in park or even in D with my foot on the brake and loading it up.
This noise that I have only happens on acceleration with a bit of load after you're cruising (ie: 4th gear @ 1,200rpm and you roll into it) and what it honestly sounds like is a mixture of detonation/air wooshing/metallic rattle type sound. I feel like I'm going all over the place so I did my best to record a sound clip - you might have to crank the volume up all the way.
I notice it the most when my windows are down and I'm rolling near curbs or concrete walls.
Any help would be appreciated before I go completely insane and pull the manifolds off, plane them and install with new hardware to cross that off the list.
