No Exhaust Valve Set CEL / MIL?

[2fast916]

As I continue to decide on the exhaust I will choose to install, I've narrowed down my options to three somewhat different exhausts. Of these options is the Remark Sport Touring (with two tips and no valve). If I unplug and remove the OEM valve with my OEM exhaust, will I experience any issues setting a CEL / MIL (going into limp mode, etc)? I know AWE offers a similar solution but, they have some sort of plug that goes on the remaining harness left in the car. I'm curious if this is only to weather proof the exposed connector or if it simulates the valve?

Thanks in advance!

I was looking (maybe drooling) at the Remark Sport Touring Ti system and found their instructions on-line. Interesting enough, step 2 states:

Without any real world knowledge, this would seem to indicate that any system that removes the valve will not set the CEL / MIL when unplugged. I'm hoping someone can confirm my theory...

Also interesting that Remark's instructions for the same system in Stainless does not have the same note / claim. I can't imagine how a difference in materials would change the statement

It does set a code, but will not cause the check engine light to come on. I had a customer with a Remark exhaust and no valve in for another issue. A dtc was stored but no light on dash.

Awesome…Thanks! I assume the code causes no driveability issues?

Nope no issues.

Nope no issues.

Thank you again

I wonder if the stored code disables Hondata pop/bangs if enabled?

I don't believe this car was tuned. It did have an issue, dtc p0087 which was a low fuel pressure code and had a bad hpfp. When i replaced that and did all etc clear, a code for the exhaust valve was still stored but no light was on. On test drive car was fine, pulled normal and exhaust sounded great, no drone. Hopefully some body can answer that. I installed an Awe exhaust for a customer and that came with a plug to install to protect wiring from corrosion i assume, that also had no light and i know for sure not to be tuned. Anybody with a Hondata what to chime in.

Could u confirm with AWE has the same?…no MIL but a code present? I have wondered if the “magic” AWE plug was just a dust/water protector for the harness connection that remains.

I did not scan his car when finished with exhaust, so no sorry i can't. I know no lights were on during test drive, or since. He came back and i installed intercooler with new piping and an intake with a turbo inlet pipe, all PRL and he had no issues. I will say that there were no pins in dummy plug, just a plug. So just assuming it was protector of sorts to keep water from plug, and not a jumper of sorts to keep a mil off.
