Help choosing headers for 5.3 Silverado.

Well my Silverado with the 5.3 is starting a manifold gasket leak and the manifolds are pretty rusty. 

 

I can’t tell you how many times I’ve changed the exhaust manifolds on my ‘98 454. They always cracked so I have given up on stock style manifolds.

 

from what I’ve read, long tube headers are the way to go. Problem is, I’m not sure which to go with. Pretty sure I want either stainless or ceramic coated headers. Not wasting my time with painted versions. 

 

Please give me suggestions on choosing the right headers and some oppinions about how to setup the exhaust from there would be appreciated.   

 

Thank you!

I bought my truck 8 years ago. The guy I bought it from had it 10 years. During that time he stroke the engine and put 50K miles on it. He put edelbrock coated headers on it. I checked the bolts once.

I’m guessing your happy with them. I’m actually looking for oppinions on headers for ls motors but will look into the edelbrocks.

Headers are headers, which ever small block doesn’t matter. I am impressed with the longevity.

American Racing and Kooks are well thought of.  The cab noise will increase and folks also report cracking with these but only after many years from what I've read.  The 5.3s cast manifolds are the most durable.  Long tubes are good for about 20 RWHP with a tune.

I’ve looked at kooks, big bucks lol. 

 

That is the first I’ve heard about 5.3 manifolds being durable. I also haven’t heard bad about them. Just going off experience with my 454.

 

Not looking for a power increase but wouldn’t mind it. Mainly looking to have a lasting exhaust without leaks. 

 

Thanks

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      The oil filter has NOTHING To do with oil leak. GM sources parts from 1,000's of vendors and as with anything mass produced, flaws are unavoidable.    Putting a larger oil filter will do nothing but satisfy emotions. The OEM filter is designed for the engine and perfectly capable of handling the demands on the engine. Oversize oil filter could result in reduced flow and overall lower oil pressure.

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.

      Diesel hit $6.00 here today at the truck stop.   Payed $2.79 for E85 today too.
