Hey guys I got my MBH headers installed.. long story cost me about $2k to install/build mid section, x pipe, motel for a few days etc to get this done but so far it seems to be a huge difference even putting around town.. one thing I've noticed is the car is still dead silent until I give it gas.. then it sounds like an RV.. I hear the valves, the air whirling etc From under the dash/console. I assume this is normal but has anyone here who have headers on their car figured out where the sound proofing needs to go? It seems pinpointed like the car is very well sound proofed but it's coming in from a small spot that isn't. Like it's very well localized. Thanks!

Found out it's completely normal everyone has it.

E42AMG???

Generally sound come in from the steering shaft hole

please post videos of the car at idle and WOT. I have been eyeing these for a while, but am hesitant to pull the trigger due to the price point. Very interested none-the-less!
