Fair comments re my headers. FWIW, I have tried dump-to-atmosphere vs plumbed-back WGs on a few cars and unless the exhaust system is undersized there isn't usually a large power difference. For my purposes I prefer the car to be a bit quieter @ WOT, hence the WGs dumping back into the exhaust stream.

Here is a photo of some iteration of 993 GT2 EVO race headers. They are large diameter, long tube and appear to be equal length. If I didn't mind driving around with ear plugs in I would do something similar on my car
