Best Exhaust Option with NPP and AFM
I can't seem to find a definitive answer on this question. I'm looking to upgrade my exhaust system from the secondary cats back. The problem is I'm looking to keep that only the NPP valves but the AFM valves as well.
Does anyone know of an exhaust that will retain the secondary cats, and also has both the NPP and the AFM valves included in the system? Most of the systems that I see will keep the NPP but do not have the AFM valves included. Feedback appreciated |

Borla offers midpipes that retain AFM.

I don't know of any cat-back exhausts that keep the secondary cats. The Hooker Blackhearts offer exhausts that keep the AFM valves. If you want to keep the secondary cats and AFM valves then I suggest you save some money and just get an axle-back exhaust. There are a number of options on the market.

I guess I am just confused on the cat back exhausts for this car then lol.
As long as getting rid of the secondary cats will give me no problems I am fine with that. I definitely want to keep the AFM and NPP though. I don't see a thing that is a complete system that includes this but again I may not be understanding correctly. Axle back is not really an option as I want to get rid of the crushed pipe |

Borla part# 606010 is their midpipe that retains the secondary cats and AFM. I'm considering this myself.
Edit: Flowmaster part# 81084 does the same thing.
