14’ Silverado 5.3L AFM muffler delete

Had my local guy delete my muffler including the AFM (active fuel management) flapper. All cats and the resonator are still on. Hard to hear the actual rev sounds through video. But you can hear those lifters talkin a bit lol GM and their dumb ideas for fuel mileage.. AFM is garbage.

I just had my 2016 Silverado done about two hours ago. I did the same thing you did, but I kept the flapper valve. It sounds great so far! I noticed the pipe they used to replace the muffler is a smaller diameter than the rest of the exhaust. I see it’s the same way on yours, so now I feel better, lol. They charged me $100.

[@3369aaron]

Nice man! That's not bad at all. Worth the $ in my opinion for sure.

[@97JoMiller]

now that you've had it for a few years, did you end up keeping it or getting a muffler? Does it cause a ton of exhaust drone or does it sound good? I don't want to deal with an annoying drone on long trips pulling a trailer

[@Squiggs2T]

Do you have to delete the afm? Or is it ok just to replace muffler with a pipe?

[@fred3x]

I have a 19' LD basically the same truck as you, gonna do it the same, I'm dumping the AFM with the range as well, I tow a 22' RV and I might do a cold intake too, more in less restrictive out, thanks dude love it!. BFG's are the bomb!

[@3369aaron]

Nice! I think it's just enough sound w no drone, you'll love it. Let me know! Thanks for the support with buying BFGs, I love my job there making the KO2s & KM3 mud terrains amongst other BFG tires! Take care

[@Savageplumber85]

Before I totaled my 2011, I had a muffler delete with a cold air intake. The combo of the throaty intake and beefy exhaust, great combo. My opinion of course. I truly don’t think you’d be disappointed.

[@andresmontes2606]

Im looking to muffler delete, weld a pipe and add dual exhaust tips. However, Im confused on the valve part. I do not want to disable the AFM so I'm not cutting off the valve. So will I still get the cabin drone noise with the valve on?

[@j_rod75]

I know this is kinda old now but look into the pedal commander. This mod in addition to the AFM delete and no muffler is a legit setup.

[@Savageplumber85]

I have one for my 12 tundra. Fucking amazing!!

[@davidjackson7351]

I have a 18 and cut the flapper muffler and resonator off and just left the cats and sounds so good and bought the range too to keep it in V8

[@spiercevaughn]

500th like 🎉 lol. I have a 14 Silverado and I just replaced all my catalytic converters last night and that was a pain…the driver side and back converter were completely on chunks all down my exhaust lol I could still hear a couple pieces back in the muffler after I got most of it out and thinking of doing this… sounds pretty good

[@redneckjoe2004]

Nice truck man! Got an 08 Silverado with the AFM 5.3, hate that shit. Also if you need a welder just holler I live in Michigan at the moment

[@DskTwreckz]

The flapper is for sound reduction that is it, nothing to do with AFM

[@augustinasvilkas]

It's there to make the exhaust sound better in v4 mode. If it wasn't there you would hear the 'helicopter noise' as some people call it.

[@3369aaron]

I didn't know that. Thanks for the info! Cheers 🍻

[@APACFILM662]

Thanks for the video and detail bro. I got a 15 Silverado and was thinking about doing mine also

A P.A.C FILM no prob man! thanks for watching. I love how it sounds, a nice rumble on start up and mild while accelerating. Perfect for the cost in my opinion.

[@APACFILM662]

kickpushcruise exactly bro. I came from a true dual 03 Tahoe with 2 10 series flow masters and mud tires. You couldn’t even have conversations in the truck or take it on a long trip cuz it gets super annoying 😂🤣 yeah this seems like the cheap better option. I do miss a little rumble.

Nope mine always cranks for a few. In the winter it's worse. I read somewhere you need to prime the injectors, so if you turn the key to on position for a few seconds without cranking it, it does seem to start a bit faster. Let me know if that helps 🤟

[@beardedyaker9767]

Do you HAVE to use the little computer to disable the AFM? Or can you just delete the muffler? I hate to spend the money on the extra step if it's not needed. I drive a lot of long-distance and love to save on gas mileage. Thanks for the video!!

[@3369aaron]

No you do not have to use the programmer but it is recommended if you are deleting the flap valve with the muffler. That's what I was told... hope that helps, do some research and let me know how it goes. Good luck 👍

@@3369aaron Thank you so much for answering my question. Watched countless videos trying to decide what to do. I think you made up my mind.

did you notice a decrease in your mpgs after disabling V4 mode?

[@3369aaron]

I can't say I noticed a major decrease, but that all also depends on how you drive, the terrain and what fuel you run.

[@JesS-rs5gr]

I usually cruise at 40 mph and Floor occasionally.. after getting the Range device I’ve noticed better mpg just buy fuel consumption. Haven’t tested the numbers yet to verify though.

[@daleliske9757]

I too have bought a similar product to cut out the cylinder deactivation. It runs on all 8 all the time, my mpg has dropped maybe .5- .7 mpg. But less than one. So... to me it was worth the $125 I spent. But I'm thinking of deleting the muffler now too after 178,000 miles. Another video I watched, the owner actually increased his mpg by 1, keeping the resonator but deleting the muffler. So, I'll gain what I lost with running all 8 cylinders. Plus have a better sound.
