I have a 2002 Silverado 3500 w/8.1 and 110k miles on it .

It has a K&N and Mobil 1 Syn which is being replaced with Amsoil next .

Under hard acceleration I get a popping sound and feel and some hesitation climbing the RPM range.

No codes or messages .

I can hear exhaust leak coming my original muffler at idle but no loud noise you would associate with a muffler in it's last throes.

Under normal acceleration , nothing .

Anybody experience this before?

If it is the muffler , I've read what you've all posted and I want the least restrictive muffler I can get without alot of noise .

It seems that equals Magnaflow .

  I'd go right back to the dealer. If I didn't get satisfaction there, I'd go to a different one. If not there, I'd contact GM. It's under warranty. It's their issue to fix.

  A lot of people also forget the old 6spd was pretty good at the torque converter snout wearing into the front of the trans case. Pretty common issue. 6spd was not a perfect trans by any means.

- Oil Consumption

  Third time. Some consumption is 'masked' by fuel dilution, soot formation, acid formation of blowby gasses. Oil consumed offset by degradation products produced. 2 to 8% How much is that of your sump volume? for Pepper that is 4 ounces to a pint of oil. Why is everyone aware that we check transmission fluids at operating temperatures due to thermal expansion and ignorant or at least dismissive about this issue for the engine oil? Ever allow a motor to drain at oil change for a period of 'overnight"? Measure on the dipstick every quarter hour for say 2 hours and educate yourself. Then let is sit overnight (cooler) and ask the expansion and dilution questions again. 😉

  $3.93 for 87 octane. $4.73 for 93 octane. $4.70ish for diesel. But a short drive can see prices swings as high as $5.30's still.
