Hey there! The engine noise around 2k is just insane. 2200? Can't hold a conversation. At least in the 2.7l.


However, this took at least 30% if not 50% of the noise from the engine away. Its not quiet as a Cadillac by any means.. But you can easily hold a conversation with it done like this.

I did the entire hood with Killmatz sound deadening (make sure to use a roller so it doesn't sag).

Then you'll want to go inside, take the entire dash apart, and seal that entire firewall up. Make sure you get the top (near the vents) with an entire layer just like the roof. I forgot to take a pic with the dash apart, but here's a pic from inside the cabin footwell. This is how far I went down. Now imagine that, all the way to the very top behind the dash. Behind the HVAC, behind the radio (see my other thread on overkill radio, amp, sub, 6 speaker setup). Above the pedals, on the sides, everywhere behind there. T30 and 12mm to take the dash apart, very simple. I just left it hanging on the wheel and reached back there to do the entire process.
