Exhuast leak?? Or normal noise??

[Idahodmax]

So, I did my sinister diesel egr delete, and now on acceleration my truck makes a different noise that I'm not used to.. it just started after I did my egr delete, generally only when I'm getting on it harder than normal too and only when the rpms are up like 2-2500.. I pokes my head around the connection points and the plates and I'm not seeing any soot build up, just curious is this is normal and I'm just being ocd

Double check the bolts for egr riser block off plate, i had the same issue where they weren't quite tight enough causing an exhaust leak tick

Oh ya, you'll have a little more of a hum and hollow sound, I noticed the same when I did my Sinister. :thumb:
The EGR kinda acts like a resonator toning down the sound, this might not be the correct explanation but it's all I could come with.
