Does the intake Mod effect emmissions inspection? What other Mods effect inspection?

 

i believe EVERY engine mod effect emissions. the intake..you should be able to pass w/o a prob.

 

The Y-pipe may effect emissions. But from what I hear, if your engine is at normal operating temperatures, the Y-pipe will not affect emissions. On a cold engine though, it may not pass. By replacing the Y-pipe you are getting rid of the pre-cat.

 

That's correct. Regardless of whether or not you can pass the emissions test, you will not pass the visual inspection with a Y-pipe. The only question is, will the mechanic actually conduct a visual inspection at the time of the smog check and if he does, will he know what to look for?

As for intakes, the only one that's C.A.R.B. approved for the Maxima is the Stillen Intake and then only for model years up to 1998. However, it's a whole lot easier to put on your stock intake before you take your car in for a smog check than it is to put on your stock Y-pipe.
