ok, it looks like i'm gonna race my friend with his mommys 2000 Z24 auto in about a week or two. my friends are actually making bets on this race... but i have a bit of a problem. due to the cold weather (i think), i blew a nice sized hole in my catalytic converter. am i gonna be losing any performance because of this? i would love to get a random tech now... but i am in college. i have no money.
