..I never even knew anything about a Dodge Demon when I bought mine ...some 14 years ago, I just knew I LIKED IT...lol.... so at least you know its worth,... agreed... everything you change make sure you can put it back ..... and keep the old parts. i gave away my stock exhaust manifolds ..... thats was stupid....I didn't like them on the car but still I should have kept them...... anyway GREAT find on the Demon....... Pic's yet????
