Default FabSpeed valved exhaust vs. Codes

At the risk of this question being asked a thousand times in the past, have any of you guys had issues with this exhaust causing error codes? Stock headers.

And recommendations this set up vs. any others, i.e. the new Borla? There seems to be a whole lot to choose from out there

As long as the install instructions are followed correctly, you will not have any codes!

Good to hear. Its not that I'm experiencing error codes with this exhaust, just gathering feedback before I make the move. Have not purchased it yet, but all indications are this is the direction I'll take.
Are you pleased overall vs. the stock exhaust? Do you like the sound?

If installed correctly, you won't get an CEL or codes.

We're a dealer for Fabspeed, let us know if we can quote you out.

With the Cicio AFM/NPP delete modules you won’t get a code for any aftermarket exhaust.

Question -- I just had a Fabspeed dual mode exhaust put on my C8 and love it -- but it threw a bunch of CELs. Do I need to take to dealer for some kind of relearn for the AFM valves?
