FAQ
What is the difference between 21103BLK and 21100BLK?
21100BLK keeps both the NPP and AFM valves. 21103BLK keeps the NPP valves but deletes the AFM valve, using a simulator bracket so no AFM check engine light is set.
Can I still make it quieter?
Yes. The NPP valves stay functional, and CORSA rates the system 1 dB quieter than stock with the valves closed.
