Can someone answer this? Most dyno graphs I've seen with bolt-ons there's a gain throughout the whole rpm band.

Can anyone explain?

Due to the factory BMW flange/mating system utilized, BMW allows flex and expansion using their unique gasket system. We have designed our down pipes to utilize the stock gasket system. Our flanges have been custom made in-house to ensure proper sealing and expansion. Using all these methods reduces the need for a flex joint in the down pipes and avoiding premature wear.

Nice. Where are the videos of the full exhaust?

Can't wait to have the Gintani down pipes installed on my 2016 M3. I drove with Alex's tuned M4 with Gintani down pipes and Gintani tuning. All I can say: awesome, incredibly fast, best exhaust sound ever. I believe it has about 500 hp to the wheels or about 600 bhp.
