True. There website seems to sell it quite well, apparently the material it is made from is supposed to be better than the others available on the market.
Have you had a remap?
No..................
Well for a start, all those claims they make are horse****.
The Zed has an intelligent ECU and will dial back any gains in bhp/torque back to OEM. Not that you would get any gains due to heat soak.
If you want something for good looks, then I suppose it's fine...although with ARC coming back into business I would wait and get an ARC kit.
If you want power gains, then fit an 06+ airbox (or convert pre 06 using rtbiscuits velocity stack kit) and spend what you saved on an UpRev tune at Abbey/Horsham/RS Tuning.
