It was asked before, but here is the answer again....

 

From the last pup cat it is 3.5" to the inlet of the muffler. Outlet of muffler is 3.5" but then immediately drops to 3" before it enters the backpressure valve. Exits the backpressure valve as 3" then steps up to 3.5" to entrance of the rear resonator. Exits the rear resonator as 3" to the tail pipe.

Is this the same for the 2013 model as well?

2013 has 3.5" all the way. I never bothered to measure but the tailpipe on the 14 5.3 and 6.2 is visually identical.

Still waiting for my SLT 6.2 to be delivered.

If I want to put an exhaust tip on, what size would I need? (ie: Inlet, outlet, length)

If you are just wanting a tip, then the GM tip would be fine. To answer your question the tip is 3" on the 6.2 trucks.

TJay74, does the inlet of the factory muffler reduce? Should I order a 3.5" inlet / 3" outlet or a 3" inlet / outlet??

Mine is 2014 6.2L and the tailpipe is 3.5". I couldn't find any exhaust tip that looks better than the GM 22911703

Looked over the forum briefly and can't find it. I'm looking to replace the muffler and cut out the flapper but I don't know what the diamaet of the exhaust is there on the pipe so I can't get some pipe and muffler. Anyone know?

 

Thanks!

3" muffler, center in, offset out. and a section of 3" pipe to replace where the flapper goes.

I measured my 6.2L tailpipe with a micrometer and the O.D. Is 3"

That's what I read everywhere, everyone says that the 2014 6.2L has 3" tailpipe. I don't know why mine is different!!

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
