Put on the front brake pads and attempted to find the source of a whistling noise from under hood when I get in boost. Almost guaranteed that it's because when I installed the Cobb intake, i thought to myself, let's just get some more airflow coming in, so I drilled a bunch of holes down 3 of the sides. The whistling has gotten worse since putting on the stratified time a couple days ago, which makes sense because of the increase in boost pressure. So I'm looking for a stock lower airbox to replace mine if anyone's got one. And for the brakes, I went with Hawk HPS 5.0 street fronts, and based on my quick 15 min test drive, the pedal feels like it has longer travel and is softer than before. Once I finished installing both front pads I pumped the brake pedal like 10 times to get pressure back into the system, any ideas why the pedal would feel that way?

Going to be a boring week. Have to pass emissions so it means no tune so I can get the O2 sensor reading.

Boo.

I have a stock airbox around. You just need the bottom?
