Exhaust on a 5.3L with Active Fuel Management
I am thinking of changing the exhaust on my '07 Silverado. It has a 5.3L with Active Fuel Management. My question is... what is it going to sound like when 4 of the cylinders cut out??? I don't want it to sound like a ricer 
I don't want to change a whole lot, I just want to add a muffler to give the truck a deepr tone, but I don't know how that works with the AFM.
Has anyone tried this yet???
Also, does anyone have feedback on the AFM system? Does it work? If I am cruising to Vegas at 85MPH, does it even kick into 4 cylinder mode?
Thanks

I think it only does it for a few seconds at a time.
