Hello, does anyone have any suggestion on how to reduce engine noise coming through the dash/floor area? After I swapped my lifters for Morels, which are definitely noisier than stock, my headers amplify the valvetrain pretty hard into the cabin. It's getting to the point where I want to put the manifolds back on, but I figured before I did that, I'd try to reduce the noise somehow. I know the dynamat stuff seems to help, I am just not sure where to put it.

Would a hoodliner help?
turn up the radio


Hybrid exhaust upgrade it's quiet :) sometime I have to check if the engine is still running

Honestly, that's what I do lol. When DVD is playing for my kid or a/c is on don't really notice it. Windows down, don't notice either.

Sometimes the simple solutions are the best solutions. The A/C fan is so loud it drowns out most noise for me.

Yeah I got used to it, doesn't really bother me anymore. It's worth it now that i know I dropped the 0-60 by a full second.

there is some oem engine bay sound dampening not sure of the part# though

go to a junk yard and swipe it off a hybrid from the firewall and hood it will quiet it by about 20-30%
