when you guys installed your headers without emissions stuff did it through a code? should i throw a code? i'm gonna buy some Pacesette LT's ORY for my 94Z A4. will it matter because it's an OBD1. no downstream O2s. let me know.

 

As long as you have a functioning AIR circuit by keeping the fuse intact, you shouldn't throw a code. With the EGR, it is kind of a hit or miss. If you do set a code, just get it tuned out.
