You may lose low end torque with the SLP runners, although they are probably the best average of the "Long runners". There is always a swap and with stock internals if you go for the higher HP of longer intake runners it can push the powerband up in the RPM range. Without a cam to go with the runners the only place you will see a noticeable gain is at the track. It will most likely be a little slower to take off ont he road.
