There was a few issues like the sensor from bank 1 hits the heat shield. I have a tune that deletes bank 2 so I just swapped the position of them. I used my muffler deleted oem exhaust and it sounds great. https://youtu.be/bUZP8hVlfKk?si=M2Ena1TtaVgRDlI9 This my video with the sound and with the different parts as the install goes.
Thank you for your heartfelt feedback! We'll keep working on it!

Fits perfect
Went on just like you'd expect. No issues with quality or fitment. Highly recommend.

Put this catch can on my ’21 Q60. Install was straightforward, hoses lined up perfectly. Engine feels smoother on acceleration, and I’m confident it’s preventing future carbon buildup.
Put these on my ’10 G37 Coupe last month. Fitment was spot-on, install went smooth, and no rattles or leaks after a few hundred miles. Noticeable bump in power and a deeper exhaust tone without too much drone.
Installed these on my ’08 G37X over the weekend, and I’m impressed. The fitment was spot-on, no weird gaps or alignment issues. Throttle response feels snappier, and there’s a nice bump in low-end torque. The sound is a bit more aggressive but still daily-driver friendly.
I installed these on my 2012 G37 Coupe. Fitment was decent—took some effort around the steering shaft but nothing crazy. Once installed, the car feels more responsive and definitely pulls harder above 4K RPM. The sound is throatier too, especially at wide open throttle. Paired with a tune, it made a noticeable difference. So far, no leaks or issues.
