Yep. The moment you touch the intake or ECU you are pretty much fubar. There may be ways and means around it via an engineer but I suspect the hurdles would be onerous.So basically the systems are illegal ? So you cant even retune your ecu ? I can understand with the changer over systems, but i always thought you were allowed to tune the existing. Exhaust mods are legal i think insurance wise as long as you maintain the mufflers and car, but the 1 5/8 dont come with a EGR valve for Genies or Pacemaker which i know wouldnt make EPA happy.
