I have a flowmaster super 40 with dual outlets on my Silverado.
The AFM Disabler has worked perfectly from day one. I am so happy not to deal with v4 anymore.
My Camaro SS is like a brand new car now. No more shuddering vibration and annoying 4 banger exhaust noise. Thank you Range for my full time V8.
Right on! Does what it is supposed to do. I still have a warranty and it’s nice to know I can just unplug it before taking it in.
Bought this to shut down the AFM and it does just that. It got rid of the hesitation of switching between 8cyl and 4cyl mode. I recommend this to everyone I know that has a Suburban with AFM.
