Pay attention you guys are saying exact opposite things here.
Headers gain 15ish peak whp... but at very high RPM the gains are even bigger.
At 6000+rpm I've seen a 30whp gain over stock without a tune or pulley.

Hopefully this is for n/a too cause I always wondered if I should of sold my headers with the top swap instead of installing them
