Not much point in dynoing, I live 5280ft above sea level.

Sounds mean as hell! It feels even faster. On WOT I usually shift into third at 60mph and now the extra power is carrying me to about 64/65 (usually the limiter stops me at 60, extra momentum is giving me a few more mph).

70 to 90+ is DEFINATELLY faster. Before it was painfull watching the needle climb to 80+. Now I punch it at a 70 roll and 80 comes in a blink.

Bottom line: it doesn't matter if they added 3hp or 12hp, my Z is now noticeably faster and sounds better.

Total cost: $430 installed.

Total enjoyment: Ear to ear.


*Slight metallic vibration under hood. Not all the time, but never happened before headers. (Most people probably wouldn't even notice it.) Any guesses as to what?

 

I installed mine this weekend as well, i felt a noticable increase in power and it sounds alot meaner

 

Great news!
But please someone DYNO so we know its not all in your butt

 

i just installed mine and i know my butt isnt lying to me, i raced my friend in his wrx from a first gear roll without the headers, and we stayed completely even, now i raced him again and i pulled half a car
and then 4th i was a car and a half and pulling so it def made a difference

 

SWEET!!!!
