Anyhoo, it might be helpful to look at different cat shields to get an idea:

Most of them seem to have around 10%-ish of the area devoted to airflow.
Hope this helps! |
i just ordered this- Falken Design 36 in. x 72 in. x 1/8 in. Thick Aluminum Composite ACM Brushed Silver Sheet
its pretty much stiff dibond. ill be cutting out venting around the muffler
will need a way to drill into body panel to attach it
will be using welding tools or heat gun to add a slight 10 degree curve towards the end and then will build a rear diffuser from there
