How could they not honor warranty? curious.

Regarding any issues with the exhaust system, not the entire warranty.  Poor wording on my part.

I welded in a borla S type 3” or 3.5” in/out muffler only. Kept the resonators. Very similar to the gm performance exhaust. No drone. Can only tell that the DFM is working when your outside the truck and it’s idling away. Other than that it’s a nice deep subtle growl till you open it up 

Got rid of both flappers too? Do you think keeping 1 or both would get rid of any DFM noise? And I assume no drone means literally- no drone at all speeds/rpm? Thanks!

Yep both flappers gone. From what I can tell, no drone. Outside the truck yes you can hear the DFM. Inside I can’t.

Thanks. Still debating muffler delete or a Borla system...the GMPP system sounds great and from what I've read is just the Borla Touring

Did you just purchase the S-Type Crate Muffler or did a shop have to order the part from Borla? Don’t mean to bring up a dead thread, just been digging through pages and trying to figure it out.

I ordered it through an online dealer in Canada. TDOT. Canada’s version of summit racing kinda. Universal 3” in/out S type

Awesome thanks! When I find the muffler I see two option with offset inlet center outlet or offset inlet and offset outlet. Going to crawl under the truck after work and order it. I love the S-Type growl, just can’t justify the cost of the whole system. You wouldn’t happen to have any videos to hear it would you?

Sorry no videos. I used Borla part # 400500

Interesting, I was actually looking at the crate muffler, part # BOR-400843.

I do not believe the #400500 is Type-S, where as what your looking at is

For clarity, left the resonators, but killed the flappers, and minimal to no drone, but the sound did get better?

 

Thanks!  Since I have the elevation, I want to leave everything bu the flappers/muffler.

Update..

 

Meant to post once I had exhaust done.  I had the Borla ATAK muffler welded in, removed both flappers and had them fabricate about 3' of tubing for me.

It is definitely loud, which I personally like.  Would leaving the flappers in quiet it down when just cruising or idling most likely, but I personally don't find it that bad.  It has a constant rumble to it at all speeds/rpm and when just cruising can be barely noticeable to unnoticeable.

 

If your not looking for loud I  would suggest Borla Type S for similar sound but quieter, or if looking for just a little punch then the Borla Touring. Like I  said if kept a flapper or both in would more than likely help with the constant rumble if that bothers you, but IMO anyone worried about that should not be buying ATAK's

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      Have considered installing a DC to DC charger in your camper to replace your isolator?

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
