What do you do with the 02 sensors when you run no cat exhaust?

You can;
1. Buy O2 sims to plug into the O2 harness to prevent codes
2. Have someone with tuning software (like HPTuners) turn off the code permanently. Usually done during a tune.

Damn i always tought you could drill a hole and plug it into the pipe are something. Where do you get these sim's seem's the easyest way.

That is what I thought.:wtf:

Sims aren't easy to find anymore and they can go bad like any other electronic part. Getting the 02s tuned out is the way to go.

Why are you running without cats? They are only worth 5-6 horse...and the gas smell. :doh:

Casper electronics used to sell them, but I think the Fed is cracking down now. (used to be around $95 when I bought mine)
Turning the sensor off will be the best way. Just takes someone with a tuner a few mins. but why not get a tune while you're at it.:thumbsup3:

I've seen dynos where guys pick up around 7-8hp just going to "high flow" cats from stock, so it does help a little. Proably about as much or more as a "zip tie" mod.
