really i dont think they will have a problem tearing that engine down..from how its plummed it dont look as bad as really a normal 4 stage n2o engine..think on a 4 stage engine u got the same amount of noid but there mostly coming off of hard lines..and the 4th is the vipor system witch is the one that runs inside the intake...its the speed techs new n2o system..but then u get also the 3rd stage running on the inside or the intake rails..

so really my 2 cents is that this system would be much easier to work with.

and marko yeah the fuel rail is its tunning system.
