Here in Southern California if you get pulled over by a cop while driving your EVO, he or she will ask you to pop off your hood.
He or She will look for the specifics to give you that emission ticket.
1. Fruity Colored BOV
2. Shiny Intercooler Pipes
3. Aftermarket Manifold
4. Bling Bling Intake Kit
5. Manual Boost Controller
6. Any many more.
An emission ticket will costs you about $500 dollars to pay off if you don't want to put the engine back to stock configuration so you can get it signed off.
That is why I decided to keep my engine bay super stealth. No bling bling mods under the hood.
The trick is to make it look as stock and OEM as possible.
My modification of choice consits of the parts below.
1. Nisei 1 piece matte black upper and lower intercooler pipes.
2. Nisei matte black intake pipe.
3. AEM Intake with custom stealth cover.
4. Stock appearing FP Red Turbo
With the Nisei intake pipe kit it relocates the BOV underneath the AEM box to avoid detection.
So when the officer gets tired of looking and decides to give up and let you go. Success!
Little that he or she knows that the car is pushing 470whp on E85
Unfortunately my exterior mods are not super stealth
But you cannot get an emmision ticket with exterior mods
