I also asked about their dyno results but apparently their test car had a speed limiter at 180 kmph (112 mph) so their car wasn't fully tested. They did say it gained about 10 hp from the testing so far though.

I love the sound of this exhaust but from what I found out so far, it's too pricey for me and will most likely yield lesser power gains due to it not being a true dual system.
