Swapping Out The Muffler And Tip Only

Is it possible to just swap out the muffler and maybe have a tip welded on? ECLB exhausts are few and far between and the only other option is having a muffler shop build a system for me. Well they use crush bend pipes and vortec muffler for the same price as a good system. Plus I dont really want to increase the size of the system. All I want is a little bit more of a deeper lope but keep the stock power curve. A chrome tip would be nice too.

 

What do you guys think?

 

The first pic is the day of purchase since then I have added nerf bars, westin bull bar, and BF Goodrich All Terrains.

It is possible and can be had for about $200 bucks all in all. I'm looking at doing the same thing and am just waiting to pull the trigger on a Magnaflow 12259 or Hooker Aero Chamber muffler. I've decided not to go with a tip since I want to stick with side exit and it'd be real obvious it was just a tip welded on. You can buy the muffler online for about 2/3s or 1/2 what a muffler shop will charge and then just pay a good shop 30 or so bucks to weld it in.

swapped out the stock muffler for a magnaflow. 22" long 5"X11" case. It's a little louder than stock when idle, but has a nice growl when you get on it. stock pipes

I did the same - only with a flowmaster muffler. It's got a great growl, and you dont lose too much backpressure.

I'm preparing to do the same - with a super 40. I tow a travel trailer so I'm concerned about torque loss, I'm hoping I won't lose any torque with the new muffler. Should I be concerned if I leave everything else stock?

I have another dumb question - which size inlet/outlet do I need for a 2000 5.3 1500? I measured the pipe and the diameter is 2 5/8" (?!?) Which one do I want?

A lot of the flow is in the pipes, not the muffler. Going with a mandrel bent pipe system provides significant performance improvement (probably at the expense of torque - doesn't bother me since I don't tow). That said, what you say about crush bends is absolutely true. When I bought my truck the previous owner had an exhaust shop put on a flowmaster 1 in and 2 out muffler (probably a 40 based on the sound) with duals out the back. The pipes were so badly mangled in the bends I'm amazed gas even reached the back. I took it off and went to a Flowmaster cat back 3" mandrel bent all stainless single side outlet system. It's actually quieter, and runs much better (but is still rumbly, almost to a fault on the highway). So, if you don't want to go full aftermarket system, I believe the next best thing is what you're talking. The stock pipe has to be better than what most muffler shops will mangle up for you.

I used 3" inlet, 3" outlet.

 

It slipped right over the stock pipes and welded in nicely.

 

I'm assuming you have a 5.3? Might not matter - they may all be the same. Thanks for the info!!!

on my 5.3L Burb I did exacty what you describe. Do nothing except cut out the stock muffler and install a SS Magnaflow 3" in 3" out of same length. Also added a SS tip, exiting at the side in the stock location...

works very well, sounds nice and has not affected my torque from what I can tell after my last 500 mile trip pulling my 8000# RV :lol:

Good move - probably the best sound for the money.

 

I still want that trailer, though... :lol:

I had Thrush mufflers on my '68 Cougar in '70. Nice sound! Doubt they're the same thing these days...

      No 12v outlets in 2026 gmc Sierra

      By PhilB · Posted

      It is possible to add your own 12v outlet to your truck.  Check out this video:   I verified via GM Upfitters that pin 31 is the same on the 1500 trucks.  The wire is GM part number 84779405.   You can get the GM 12v outlet from Amazon  https://www.amazon.com/Genuine-Accessory-Receptacle-25774623-13549530/dp/B0F1H9YRGF EWAY 12 Volt Power Adapter for GM   https://www.amazon.com/EWAY-Chevrolet-Silverado-Cigarette-Ignition/dp/B0915RRW6Q/ref=sr_1_1?   I just haven't figured out a good place to put the 12v outlet in my truck.   Some people are getting USB-C to 12V adapters  https://www.amazon.com/WYMECT-Cigarette-Lighter-Socket-Adapter/dp/B0F87WNQKB/ref=sr_1_1_sspa? Not sure if they provide the correct amperage that a device like a tire inflator would need.

      Wiring Help, Please

      Thanks; I looked there a few minutes, and I think I can find something. I really never looked there, as I thought it was stuff like PTO/aftermarket bodies/accessories like snow plows.

      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.

      Different requirements for oil filters?

      By Grumpy Bear · Posted

      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. 😉
