surprisingly my stock extractor is the lightest amount all; but the design is like 'deer head' and not really looks good too and it affects the exhaust flow too.
If there is a chance, I will plan to try out the ZC31 extractor.
ZC31 - Swift Sport - 5.6kg
Rs Racing 4-1 - 4.8kg
ZC21/11 - Normal Swift - 4.4kg
