Are you tuned? You probably maxed out your fuel pump because the catless downpipe let more air flow through than normal. Factory tune and Hondata basemaps handle this differently but usually 'power loss in the middle of a pull' is fuel pump related.

What map are you using? I usually only work with Hondata but I can take a look at a datalog if you manage to replicate this while recording.

Hmm. Strange.

There's no traction control on KTuner besides the factory traction control, so it's not like it was retarding ignition for wheel spin.

Did this problem only start after you added the downpipe? I can't really tell you much more without seeing a datalog of when it happens, sadly.

So as of now I just have it connected and attached to the frame not inside downpipe ( secondary 02)

Have you checked out an O2 sensor extender? I have read some good results coming from that product, and it can fix the cel issue too.

I don't think that would cut power, it would just throw check engine lights. But I don't think I've ever heard of someone leaving it plugged in while attached to the frame, either, so I could be wrong.

Did the loss of power remain after or did it just not pull as hard one time?

Would it be too much of a high gear pull?

This may sound like a noob move, and probably isn't your problem, but I'll tell it just for kicks. My DIY cold air intake came loose one time, the MAF sensor and all. Man, the car does not run well at all with the MAF disconnected. It did run though, which surprised me. I was so relieved when I saw what the problem was. Easy fix, but I was quite worried during that commute.
