So today I ordered the Magnaflow cat back exhaust part# 15318 single 3.5 in. Side exit. I'm hoping this fixes the over bearing CAI noise.

 

This seems like you are saying the way to handle increased noise in one part of the truck is to increase noise in another part.

Zero benefit other than not having to replace a paper filter every 24K. Most dry oil filters actually let larger particulates in the engine....IMO these products are snake oil and the benefits are no

Installed an S&B tonight. Install was easy. The air box is a bit bigger than stock, rests pretty close to the headlight plug. Have the butt dyno scheduled for tomorrow:).       Sent from

I am use to exhaust and intake noise, now I just have intake noise...so the answer is yes! it will soon sound like a truck with 420 ponies under the hood.

I can dig it. If my foot starts hurting, I'll hit my head with a hammer.

You mean 440-450 ponies under the hood after those mods. :thumbs:

I wanted to get rid of that ugly and restrictive box shaped stock intake tube on my 2014 6.2L Silverado, but didn't want to go aftermarket, mainly because they are overpriced for what they are.

I wanted my engine to look oem, so I looked into the Airaid intake tube, but it was only available for the last gen trucks. By looking at the install pictures of different intakes of both NBSS and K2 trucks, I decided to bite the bullet and buy the Airaid intake tube (200-996) from amazon for ~$130, and do a test fit. If it didn't fit then I'm out the return shipping.

Both NBSS and K2 use a similar stock airbox design, but I was afraid that I'll have clearance issues with the alternator, since it's mounted on the passenger side on the K2, while it's on the driver side on the NBSS.

So I got the intake tube, removed the stock tube and did a test fit, well, to my surprise the fit was great, like it was built for my truck, the alternator cleared by a mile.

But the problem now was that, the NBSS use a single 3/8 breather hose, but the newer trucks use dual 5/8 breather hoses, so I bought a couple of 5/8 fittings from the help section at autozone, and 3ft of 5/8 hose.

I took a 5/8 drill bit and drilled the existing hole, plus another spot that was right under the existing hole. The fittings were cut and JB welded to the tube. Meanwhile, I took one of the stock breather hoses and sliced the plastic tubing, that will be used to connect my hoses.

I installed my modified tube, and took the truck for a test drive, the throttle response is slightly better and it sounds great, plus the engine bay looks much cleaner.

The cost of the fittings and tube was less than $140, I decided to keep the stock air filter for now, but might get a nice dry filter later down the road, too bad it got dark and didn't take a finished picture, I'll try to post a couple more tomorrow.

The install does look clean but can you elaborate a little more on "it sounds great"? I wouldn't think that there would be a whole lot of difference from stock

It sounds completely stock, but above about 50% of the throttle, I can hear some growl, not too loud unless I'm at wot.

That Airaid intake looks nice. Although, I wouldn't trust JB weld to hold that fitting you added on.

I agree with the no JB-weld. I would be looking for rubber grommets and some tight fitting nipples or just teeing off the original smaller vaccum nozzle coming out of the intake. I would have to have it in my hands to know for sure though, but JB-weld was never more that a fix to get me home in the past. Maybe its improved over the years.

 

I love how clean it looks though... That's what factory should look like. I think I'm going to drop the cash and do this myself.

Thanks, the JB-weld is just a temporary fix. I'll drill and tap the holes for a more permanent solution.

Just a note but the K&N now includes the coupler for both 5.3L and 6.2L engine. Part number K&N 63-3082 is for both.

      286,740 Mile Services   8/6/2026   New AC Compressor. Refrigerant oil and dye, evacuate and charge system.  New exhaust system from cat back.  New Iridium plugs plus replace #3 coil Repair/rewire headlamp wiring (passenger side) and replace all forward bulbs. Polish lenses of both assemblies.  Pull rear rotors, clean and adjust parking assembly. Inspect, clean and grease front calipers. Check pads and shoes.  4 wheel power bleed of brake system. Dot 4 Reset idle speed 50 rpm higher New Serpentine belt.    Will need new pads in the rear in about 5K more miles.    Tax Title and License out the door just short of a grand.    AC clutch had bitten the dust. 1 year warranty on the pick and save replacement. Thing will make a Polar Bear cry Uncle.  He spent quite some time on the wiring. It was in the harness and he does nothing half. I got off cheap. I have considerable more light down the road. Sylvania Silver Star replacements.  Gas seal between the porcelain and shell of plug #3 was blown, cooked the coil. That was the cold miss.  Love the new exhaust. I can sneak into the neighborhood again.  Nice to have a working parking brake again. Belle Tire never got it done. That was disappointing.    This was one of her bigger bills and still way cheaper than a payment even given the oil consumption. This thing cost me under a hundred a month in repairs and normal routine costs. What is my incentive to replace it? 🤔

      cam upgrade in CA

      By AidenVorpagel · Posted

      hello I recently bought a 2012 gmc 1500 with a 5.3 and have a AFM disabler on it I'm interested in doing a cam but I'm worried if I remove the AFM system I will fail smog does anyone have info if they are able to detect that or a work around to it (not talking about hot smogging) please let me know thank you

      Possible lifter tick after DOD delete

      By B14Sierra · Posted

      Update. I started chasing down my symptoms. Started first with pulling valve covers and looked at everything. Everything looked good and couldn't hear or feel anything different. Then a compression test. 240 psi or really close on each cylinder. I was worried I was a tooth off of timing. Not bad for an engine with 173,000. Granted I did put new heads on. I sprayed water around the injector area to see if I could hear a change. Nothing. I hooked up my new hp tuner which I should have done in the first place but I don't really know what I'm looking at just yet but am learning. I noticed the fuel trims were way off so that told me I have to have either a bad injector or exhaust leak. New injectors, so I did the shop vac on blower and in the tail pipe. Sprayed soapy water and found the exhaust flange on the drivers side was leaking. I didn't think it would be that considereding I pulled the heads and left the manifolds attached. I did have the transmission replaced not long ago. They must have not seated them properly but I guess I didn't notice. I put in new gaskets on both sides. Which by the way isn't a bad job but I had a hard time getting them to seal right. Took two attempts. Reset the fuel trims and the ticking is gone, engine runs smooth and acceleration has improved. Got to feel the real difference with that stage 1 cam. It's not that big of a difference but it does add a little more. It feels like how the truck should have been from the factory.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.
