yeap... but this only applies when u changed ur headers as well...BLaCkHoWLiNG said:
last time after i changed into 4-2-1 headers without changing the midbox, my fuel consumption was terrible... within 1 week, i went back to the workshop and get the midbox replaced with highflow midbullet... now feels much better adi....
so, if u are still using standard extractor/headers, there isnt much difference by jz changing the midbox....
PM kent, he selling zenden midbullet as well... there are some picture of midbullets in his thread in zth marketplace... go n take a look....gohkokeng said:
