Switching from HFC to TP

Hey I'm just wondering if I should expect to throw a SES/CEL if I switch from a high flow cat to a test pipe. I have it tuned and have never had an SES light with the HFC with the fouler on it as it is now. Thanks!

I Dont understand what you mean by fowler, do you have just the stock 02 sensor? if so you will throw a code. If you have FOULER's or an 02 fix, youll be fine.

I meant fouler. Typo sorry. Yea I have the extension on the rear O2 even with the HFC and planned on transferring it over to the TP.

That would work well?

is this a permanent change or just for track days?
