I have CAI in my s2000 and I am considering an air bypass valve. I've never put one in a car before so I was just wondering if I should expect to do any cutting? I was told by a friend of mine that I would need to cut the pipe. Anyone know about the installation?

 

yes you do need to cut the pipe in order to install the bypass valve

 

what is the point of a CAI if you're putting on a bypass valve? You'll have the same HP gains as any other short ram intake.

 

I guess for the sound. I got it for free from a friend who had it on his S and then sold it. CAI won't add much HP anyway to an S2000. I'm just scared of hydrolock.
