The main difference is in the design and choice of pipe sizes and pipe lengths.
PowerZone is the only brand in Malaysia that has extractors designed from the ground up, by using formula and calculations to determine the design, and it's a tuned length extractor. PowerZone does not copy others, every design is original.
Other PowerZone features include:
1. Quality workmanship
2. Internal surfaces are cleaned and grounded to promote smooth flow
3. All extractors are designed with OEM fittings, no messy joints or welding, and installations are reversible.
That's why PowerZone costs a bit more, with proper R&D, engineering design, custom built, details on flanges and welded joints, etc. All these cost something, but no efforts spared for the benefit of you customers!
