Just a question. Or point me to a thread where this is mentioned? Did anybody do a muffler AND a resonator delete? I've heard the muffler delete and want something a little louder. Straight from the first 2 cats to duals is what I'm interested in. I'm going to get some kind of tune/programmer to disable the AFM.

 

Thanks in advance fellas

I had my truck just the stock 2 cats then the 3 inch pipe into 2 2.5 inch pipes before the rear axle. no mufflers or resonators or 3rd cat. was incredibly loud. I loved it but driving anymore than 10 minutes it was excessive had to throw my flowmaster super 40 back in. I wouldnt suggest it for a daily driver but its your choice if you want crazy loud go for it

How much knowledge and experience do you have with the GM Borla?

deleting the resonator does make a huge difference. i replaced my muffler with a flowmaster super 44 and kept the resonator. drove with it a day and wasnt satisfied as i didnt get the noise i wanted. removed the resonator the next day and BIG difference. really happy with my set up now

Thanks guys I appreciate it! I'm probably gonna try to do that first. When you remove the 3rd cat did it set off any codes?

No it doesnt. there are no sensors behind it its basically just another resonator

So doing this wont throw any codes or void warranty with GM since its past all the sensors correct?

My service manager was told by the mechanic that changed my oil that I had removed the 3rd cat, He mentioned it to me when they were finished and I asked was that a problem and he said no not really and in his mind would not void anything. It does not throw any codes it's not a monitored cat just some California Bullshit!

Did you find with the resonator in it sounded like stock? Or was there just not as much noise as you preferred? I just got the super 44 installed and the shop recommended deleting the resonator, I find it just a little to noisey for my liking, and might get the resonator put in, or another one. Thanks

      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.
