I'm looking to long tube headers and Y pipe for my 2014 Silverado 5.3.

What brand do you think have the better price/quality ?

I'm very interested in the Speed Engineering kit:

What do you think about ?

Any experiences ?

And most important: the headers fits good or I have to be mad like usual to install them ?

Thanks in advance

I installed mine 2 weeks ago. Have the headers and y pipe v-banded to ensure no leaks. That is my only complaint is the slip fittings leak and have a little play. Other than that install was a breeze. My setup is 1 7/8 headers, y pipe, 3.5" exhaust into a Borla XR1

It is very interesting, also for the bypass valve and the good price, do you have the TVS1900 or the TVS2300 ?
My truck have the Flex fuel sensor, do you know if it works good with it ?

Kooks, American Racing Headers and Stainless Works are the best for these trucks. There are cheaper options like the ones you showed, OBX, and PaceSetter but they don't always use the best 304 tubing, it will often be much thinner than the first three I listed, fitment will be poor at best, while KOOKS, ARH or SW will fit perfect and last a lifetime. 

 

But you are comparing $500 headers and Y-pipe to a $1,500 set, so there is a big jump there. If you are going cat-less, you will also need to have a remote tuner or dyno tune done after the install to turn off the Check Engine Light (CEL) You were talking about a turbo before, decided that maybe a supercharger might fit your build a bit better?

Nothing wrong with Speed Engineering headers at all.  If you can afford to step up one notch, I would go with Texas Speed, the build quality is slightly better, and they use seamless primary tubes, so they may last a little longer.

It's gonna be loud as hell lol.

 

Prepare for loads of terrible sounding rasp and drone. Or just wear ear plugs.

Yes, I'm still thinking about but reading the comments and knowing about the bypass valve, I think that maybe the supercharger is a bit better for a daily drive also considering the easy installation compared with a turbo, especially for our mechanics that don't know LS engines very good.

Do you can suggest me a good tuner ?

      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.
