Does changing your head lights or exhaust void your cars warranty?

i drive a 2006 nissan Altima and i%26#039;m thinking of putting GReddy EVO 2 Catback Exhaust System on my Altima along with neons and halo head lights. also does tinting tail lights void warranty?|||The catback may be a violation, you should call your nissan dealer.|||As long as you only do a %26quot;cat-back%26quot; system, you%26#039;re okay. headlights and taillight mods are no issue with warranty either, though your local law enforcement can give you a fix-it-ticket for those mods.
