A8 Exhaust Questions
I've been reading the forums for awhile, and can't really find a solid answer.
I have a 2017 A8 2SS. I want to get a full exhaust, I have the NPP option. I was thinking of going Corsa/Borla but I can't find one that supports AFM? I don't really want to keep AFM but I don't want to throw a check engine light at the same time. Any suggestions on exhausts for the A8 cars that won't throw a check engine light? Thank you. |

Prepare to pay premium dollars for the NPP version of the exhausts. The exhausts for our cars are ridiculously priced as is but, when you add in the NPP, the prices jump up even higher.

There are several NPP versions but only a few make a significant difference between open and closed. The Corsa and Flowmaster have the biggest noise reduction in closed mode. The Flowmaster is half the price of the Corsa.

You can save a few $$ by getting an axle-back instead of a cat-back. If you’re keeping the cats then there isn’t much benefit to paying extra for the cat-back.

AWE has the AFM valve simulator that essentially allow the A8's to run catbacks without throwing a CEL. I ordered one and plan to put it on in a couple of weeks.

My main scare is throwing a check engine light because of AFM. I was thinking of getting a cat back. Thank you all for the responses though I appreciate it! And yeah, the NPP options are very expensive. I do like having that option, just incase. |

What the exhaust manufacturers are saying is the mid pipes delete the AFM valves, and that causes a CEL. I know Borla has a mid pipe that keeps that AFM valves, but that shit is $$$. Part number 60610.
Honestly just skip getting an aftermarket mid pipe. I wish I didn't. That would have been a lot of money saved.

Here’s a link to their explanation of the product. They guarantee no CEL. Here’s a link to them installing it. For $35, it seems like a very simple solution to deleting the AFM valves while still making it easy to reinstall the valves if necessary. |

All you do is turn off the AFM valves in the FSCM controller via HPtuners and you won't get the CEL for the valves being removed from the exhaust. It costs 50.00 to license the FSCM and I don't believe it trips the flash counter on the ECU(don't quote me) for those that are worried about warranty.
