Hey guys.

I'm interested in adding the Z-Tube to my G35. From what I hear, everyone seems to be pretty happy about it, and it deffinetly seems like a very popular mod as it adds some power at higher RPMs but mainly because it gives a nice deep sound at the upper RPM range (which I love without it being obnoxiously loud like a fart can on a civic)

I got the upgraded 7(? i believe) year / 100,000 mile warranty for my car though. Does anyone know if the Z-Tube void this warranty? And how hard is this piece to install and remove incase I ever did bring it in for warranty work and I didnt want them to see this part (assuming the problem is something non related to this piece)

Thanks!

i dont think it voids the warranty b/c it is an oem part.....install is pretty simple once you understand how to do it, not that bad, i love the sound improvement

should not be a problem at all.... if you are worried, swap it back before you go see the dealer.
