huakenny, PMed you on the pricing.
Yes, its different from Pivot, especially in terms of performance. Refer to the DYNO chart by Speedworks where we have sent our car for dyno, you can see torque and horse power improvement over all range of rev. This VS is designed for multi rev operation (similar to one of the Hot Inazma VS but ours cost few times lesser) while Pivot and similar only target certain rev (usually at lower RPM). Ours also come with a battery indicator. Ontop of that, 180 days care warranty which I dun think any VS in the market gives you that. Also, the reason we introduce our VS is because we find that almost all the VS in the market serves more as a decorative/cosmetic item more than performance which also comes with fancy colour cables.
Currently, our VS does not come with grounding wire.
