Exhaust Replacement On My '00

This has been put off long enough. My Cats are shot and the e-test is up & coming. So I want to re-pipe.

 

The magnaflow cats (http://store.summitracing.com/partde...part=MPE-93419)seem to be the best stainless kit out there and the Gibson extreme duals are the ticket for my longbox. http://store.summitracing.com/partde...part=GIB-65007 (Not looking for an obnoxiously loud exhaust this time)

 

We get loads of salt on the roads here so I want everything to be stainless/corrosion-free.

 

My question is about headers. Do I go for stainless steel headers or regular steel headers coated with ceramic? The stainless model from Gibsons has a nice thick flange (3/8”) and is 16 gauge construction http://store.summitracing.com/partde...art=GIB-GP116S

But is stainless a durable material? I want this system to LAST. The edelbrock headers seem to be of similar flange and gauge http://store.summitracing.com/partde...5&autoview=sku and could save a bit of quid by going this route compared to some of the other ceramic coated steel.

 

 

Will these “shorty” headers match up with the replacement cats I’m getting. I’m assuming a direct swap, am I way off base here? Thanks in advance.

PS Anyone ship Summit to Canada? Any suprise costs? Thx.

My opinion is to keep the stock exhaust manifolds. It will make passng the emissions tests much easier.

I would agree you should either stay with stock exhaust manifolds or consider the dynomax hi-flow cat/header system. I replaced my cats with a stock GM Y-pipe primarily because I'm getting up there in mileage (199K) and I wasn't going to keep it very much longer it didn't make sense to go with the dynomax solution.

The shipping to canada is a complete surprise, they don't tell you what the cost is, they just let you pick slow medium fast and tell you youll get charged after.

Yeah so my reason for headers was an apparent leak in the manifold but its a manifold bolt that's snapped on the drivers side closest to the firewall. Great. So they're gonna stay on there for a little while, or until the next one along lets go. I guess I'll take that $$ and replace the Oxy sensors to get some mileage back!

 

The magnaflow cats will end up just more than 1/3 the price of the GM set so that's a no brainer.

 

Thx for the replies

      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.

      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. 😉
