i have no cat on right now cuz im gettin a swap in my eg, but im just curious is it bad to drive the car runnin straight out of the header, im juss curius b/c im about to go take the car out for fun, so warn me before i do if it could **** my car up... thanks in advance...

 

lets see, it sounds like ****, people will go deaf, you will go deaf, and cops are gonna be on your *** like stink on **** in no time. Done deal. There ya have it. You could also melt some **** under your car. So make sure you run it right by your gas lines

 

you will die from exhaust fumes if you dont roll the windows down, and the sound will be so loud you wont go over 3000 rpms. it's really not fun to drive open header on the street.
