Hey hey hey. No knocking the ZEX kits.
The bad part I have found with ZEX is that purple NMU. That thing is bulky. The longest part of the install was finding a good spot to mount that thing. The nitrous is the same. Well at least if you compare a 55 shot of NOS to a 55 shot of ZEX(we already discussed what NX's idea of a shot was).
