What i wanted to find out if it's possible to get at least 50% of catless header gains with doing all the other bits.

Alot of people have tried it, power blocks, intake snorkel, grimmspeed cai. throttle body, tune, catless headerback. Yields are close to 50% but nothing like it and require real fine tuning and don't do as much as header for the torque dip.
