Hey fellow honda owners! I have a 5th Gen Prelude, basic bolt-ons headers, intake and cat-back exaust...
The problem is whenever I install my Test Pipe my check engine light kicks in, but i notice it only kicks in when im cruzzin under 3500 rpm, but if if i cruise above 3500rpm the light doesnt come on. I love the sound of my car when its on but since gas prices has gone wild i cant keep driving above 3500rpm on the street.
Some people say its my O2 sensor i need to change it, but they dont own Lude's.
So im asking my fellow Lude lovers do you have this same problem or do you know what the problem could be? Im just sick and tiered reseting my ecu everytime the check engine goes on!
You will always throw a code with a test-pipe. If you don't have a cat, then your secondary O2 will cause a CEL. You need at least a secondary O2 workaround. Keep in mind that depending on what state you live in, the car may not pass smog with a test pipe.

And what is with people jacking my sig?!?!
Im happy to make them on request but hate when they get hacked to hell by someone else.
There are spacers you can buy, that set the o2 sensor back from the main flow of the exhaust. A buddy of mine uses it, and doesn't get any CEL. I have an 02 simulator from when I had a test pipe, unfortunately Casper stopped making them though.

Workaround? not to familiar with that! yeah I live in CALI and we have all sorts of smog regulations!

One or two on the secondary O2 or were you asking if I used them on both O2 sensors? The answer is I only used it on the secondary O2 sensor as that was the one throwing the code and the primary shouldn't be affected since it would be before the high flow cat.
