I have been contemplating the idea of getting Nitrous oxide for the past couple weeks now, and called around different shops in my area, I called 4 in all. They all told me, they only will install the zex system or venom. they won't do NX express or Nos. One shop said that only the dry system will work, and they other shops say that both will work and recommended wet system. Three of the shops said Zex is the way to go for price, safety and installation, the other shop recommended. the prices on zex kit(wet system) installed with bottle warmer and tank filled is 750.00 plus 300 for installation 100 extra for stealth installation. For the Venom 1000 (dry system)he quoted me 1371.00 installed with bottle warmer,remote opener and tank filled. Then i call ARD to odr a kit and have a shop install it and they tell me that Zex wont work. that venom is the only one that will work.So what is the deal :dontknow: which one is it. Does anyone have Zex or are these shops blowing smoke up my ass. can someone clear this up for me.
