I'm coming from MN to CA and was wondering if my car would pass. I drive a 96 Eclipse GSX with apexi n1 exhaust, greddy BOV, Turbo XS boost controller, air intake so could you please tell me?

All I can say is: get it checked. It's hard to tell cuz California has the strictest air quality rules in the entire nation. It sucks sometimes...

do for thesmog test do they look to see what you have done to your car or just check the exhaust. What happens if you fail?

The intake could definately cause you to fail, not sure about the others ... Neuspeed's intake is CARB-approved, but most/all others are not ...

Anyone know about exhausts? I'm trying to keep my car legal but wondering what I could do engine-wise to get some more power, its stock right now ... K&N with Neuspeed chip &/or Neuspeed intake are legal but don't know about anything else.

So the air intake could so then the BOV could to cuz thats connected to the intake right?

Take it to a qualified smog shop in MN and ask them if they think it will pass in California. They should know about all the rules and regulations.
