GM 6.0 Gibson Exhaust 

Afm?

​@Skkell active fuel management. Will turn off the fueling and spark to 2 or 4 cylinders making your v8 a v6 or v4 to save fuel on the highway. Dumb bc its proven to cause premature lifter failure in gm motors

How do you think the factory does it 😂😂😂

It’s stainless

Good question. Basically the exhaust is loud at regular driving rpms. Sorta tricky to put into words, but if you look up a video it makes perfect sense

Drones horribly though. I’d rather have no muffler than a flowmaster

The internal baffles broke and were rattling.

@@TechnicianRed was this before or after the misdiagnosed 02 sensor?

@@usmarine4700 not sure what "misdiagnosis" you are talking about.

​@TechnicianRed he's gotta be baiting you lol. What 02 sensor? 😂

@@dumpnutz756there’s literally an O2 censor in this vehicle… Many of these internet “mechanics” in the comments have already pointed it out on this video lol 😂 He even made a 2 part to this truck with the O2 censor lmao 😂
