Stillen headers have shown to lose some of the low end torque as well as make minimal gains up top. They've also had issues with fitment and not lining up correctly for HFCs/TPs/RTPs & CBEs.
The few that have bought them would say don't buy them, it hasn't shown to be worth the money.
Now Fast Intentions just release long tube headers and these have shown both TQ and HP gains, impressive ones no less.
