What low pass filter did you use to tap into the stock head unit?
What's the baby filter?Installed an ECS Big Bore Inlet Pipe and APR Open Intake. Was pretty straight forward although i would warn anyone installing the Big Bore Inlet, that the stock intake pipe would absolutely not fit over the new inlet. I had to use a heat gun and warm up the end of the stock plastic pipe to wear it would expand/give just enough to slip over the new inlet. My car is a 2022, so i'm not sure if the stock intake pipe is a slightly smaller diameter than previous years but it was definitely not going to go over the new ECS Inlet.

Silly question but did you buy the MK7 option or the MQB?
Probably hard to tell since you did the JB4 at the same time but do the coil packs make a difference?
