This will be for daily driving and a bit of canyon carving. Track use will be almost non-existent on this car.

By the way, I can pretty much guarantee that the dip is not a placebo effect or imaginary (not sure what the actual numbers are, though), you can definitely feel it in day-to-day driving.
The most likely cause is cam phasing, which is why Dimman mentioned it, until camshafts are produced for this engine NO bolt-ons will remove the torque dip, but the nameless setup has made it better.

Remember that once you change cams you will have to make sacrifices, it will either be smooth midrange, low end pull, or highend power, not all three.

Taiman, would you please update everyone on how the torque dip has changed since the exhaust intall, and what your current driving impressions are regarding said torque dip?

Thank you
