Can anyone tell me what the major difference between the greddy evo and the evo 2 (besides the stainless piping), because I meant to order the evo 2 and I got the evo, and I am trying to decide wether i should just put it on, or send it back. Someone told me that the evo has more threads, and i am not sure what that means. Thanks for the help.

 

I believe it's pretty much the stainless piping.
