This is bullshit. All of it.

I have already posted many times on how to make power from an exhaust:
Y pipe as close to the header collectors as possible, to a single 3" exhaust. You do not lose power from "lack of backpressure"

Everything else out there is a muffle, which will give next to no noticeable gains.
