We weighed many of the more popular ones and the ONLY one that is actually really lighter is the Akra.

This includes connecting pipes in most cases. Some are actually heavier once connecting pipes are put into the equation! I will not mention which ones these are but they are very popular.

Ours is around the same as stock. You have to expect this from a proper valve system which works and doesn't lose power.

Or we can make one that's significantly lighter but just doesn't work.

Other option is to use really thin matierials but you get sound radiation which doesn't help with drone.

Your real world performance just won't be made much better with losing 5 kg unfortunately. That's the difference between one person and another in most cases.

The biggest weight loss from a full system is 23kg which is the Akra and even then it doesn't really help on a car that weighs over 1.5 tonnes.
