After quite sometimes installing the Powerzone extractor, during the 2nd day of Hari Raya in Penang, i went to SpeedWorks to install the high flow centre bullet for my exhaust system. i didn't have the picture as i forgot to snap it! And it also very leceh for me to take pictures if the bullet under my car. So i just google'd a picture of it and yeah, i can feel only a lil beat of a smoother power mostly from the low end as the air flow pressure restrictions is less.
For your information, a standard centre bullet has more restriction thus restricts the flow of air through the exhaust at the early rev, so by using a high flow bullet, u will gain a lil significant low end power, but i still think that it is not a really necessary mods. Other than cosmetics when u lift the car using jacks!
