extractor 4-1 and 4-2-1

ur car is an everyday car??...

get 4-2-1 extractor den...

if u are using ur car as trackday car... get 4-1 extractor..

4-2-1 are more intended for low revs and mid range. This helps during city driving or when u need just the right kick to overtake.

4-1 are designed for higher rpm range. I don't think this is appropriate as you don't usually rev ur engine that high most of the time.

Anyway, I don't think it is wise to change the extractor. A wrong design custom extractor will cause lots of problem to you such as loss of power. It is vital that an extractor measured and bent properly. If you still insist on changing, I would recommend hot bits extractor as I previously had on my satria and it was good.

R3 way to go man!!!

For hot bits extractor, you can start with speedworks at jalan 222, PJ. They carry the whole range of hotbits products

errr.... i dun think r3 is suitable for 1.3.......
