Weight comparison for Swift extractor

Below is the weight comparison between ZC31, Rs Racing, and ZC21/11 extractor.
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

The Swift engine firing order is 1342 so the original cast extractor is a 4-2-1 configuration. For the swift sport, it looks like a 4-1 from the picture taken (sorry can not confirm cuz picture did not show the tube connection clearly. Swapping a 4-2-1 to a 4-1 may result in lost of power band at the beginning of the rev but boost the power at the back end. So i am not sure if it is a good idea to swap the extractor (if it is confirmed 4-1), would recommend to use a 4-2-1 which is more friendly for Daily drive. :)
