Next up Headers!

Hahaha. Gears are next for sure. I heard a rumor that 5.13s and/or 5.29s might be coming out so waiting to see how/if those pan out. Not sure if a SC is totally worth it for me. I almost rather use that as a down payment on a sports car to get my

 

ive been looking into this as well... I know you did install yourself, but could you give me a ballpark number for parts??

Should You Add Headers To Your Tundra?
Jason Lancaster | Jan 04, 2010 | Comments 30

When it comes to adding power to your Tundra, replacing your stock exhaust manifolds with headers is an option worth exploring. Stock exhaust manifolds are typically designed with low cost in mind, and on many vehicles they are restrictive and inefficient when compared to after-market headers. On most vehicles, replacing the stock exhaust manifold with headers will remove flow restrictions inherent in the standard system and scavenge as much exhaust gas as possible out of the engine. For most trucks (especially trucks made more than 5 years ago), headers are a great way to add decent power to a stock engine.


Tundra owners wonder - headers, or no headers?

However, fans of the 2nd-generation Tundra know that the stock exhaust manifold on the 4.6L and 5.7L Tundra is actually quite good. In fact, the stock exhaust manifold on newer Tundra trucks is one of the more sophisticated factory exhaust manifolds you’ll find. They’re an efficient stainless steel 4 into 2 into 1 design, a configuration that’s known for moving exhaust gases quickly. The Tundra’s stock exhaust manifold tubes are also equal length for each cylinder. Equal length tubes are important because they facilitate consistent back pressure in each cylinder, improving overall performance.

The bottom line for 2nd-gen Tundra owners (07′ and up models) is that replacing the standard exhaust manifold with a set of less restrictive after-market headers isn’t going to result in huge gains. Still, that’s not to say that adding headers to a Tundra will have no impact.

On a stock Tundra, after market exhaust headers will add at least 10 horsepower. Just like cold air intakes and cat-back exhaust systems, headers work best on trucks that have other performance add-ons. The more performance equipment you have on your truck, the more power a set of headers can add. If your truck already features several other modifications, such as an intake or cat-back exhaust, a UniChip engine tuner, a TRD supercharger, or other power-adders like a turbocharger or nitrous system, then headers have a lot more to bring to the table.

Put simply, after-market headers are power multipliers. While stock Tundras will notice only modest power gains, modified trucks will greatly benefit from a set of after-market headers. Of course, headers do have some downsides:

• Expense. Depending on the type of material used, headers can range from $300 to more than $1,000.
• Slight reduction of low-end torque. Critics of headers point out that many header designs sacrifice a small amount of low-end torque for higher rpm power. Proponents of headers feel that it all balances out in the end – especially on trucks with other accessories.
• After-market headers can crack. After-market headers – especially ceramic headers – are typically more vulnerable to cracking than a stock exhaust manifold. However, it should be noted that any exhaust manifold or header can crack under the right circumstances.

Like a lot of performance truck accessories, there are trade-offs that come with a set of after-market headers. However, if your Tundra already has other performance accessories, or if you’re looking to squeeze every ounce of power from your Tundra, headers are definitely worth considering.

 

LOL I love these copy and paste reviews.

This review revolves around shorty headers. Which I agree with 100%. The stock shorties on tundras are actually pretty efficient and you can't really gain any power with a direct shorty swap. If you read the review they mention this is for a "set of less restrictive after-market headers" which is not LT headers.

The majority of the convo on this thread however is about long tubes. A different game. These are proven to add more torque and HP to these trucks especially when paired with a 3" full exhaust and tune. There are dyno's to prove this from vendors and members on here including myself.

 

Thank you for your insight sir.

As I said to begin with it was an article that I was reading and someone asked me to repost what I read. I apologize to you and the site for Not knowing

I was doing research on my own to see if this was an option for me when the original thread began.

 

No apologies needed . I was just shedding some light on the posted article because they can be misleading.

If you want to learn more I would def call up Keith at @dirtydeeds. That guy knows more about exhausts for these trucks than any article out there. I have yet to find an unhappy customer of his.

 

^^definitely recommend this suggestion.

 

IMHO

If you're investing the first time do 488 on 35s. Yes your RPMs will be a little bit higher but the overall performance will be significantly Leaps and Bounds better than you going from a 430 to a 456 you will actually be happy with the $3,000 investment.

So RPMs will be a little bit higher due to Gering but what really matters across everything is the fact that your engine load will be less. The engine will be spinning a couple hundred RPMs Haier but the engine is working less (powertrain and driveline in general) and engine load is less - that's the most important thing.

 

I like the idea of JBA Long tubes, an open exhaust, and a DAP tune for the 5.7L

FYI: When you replace the factory exhaust manifolds with JBA short tubes and do nothing
else to the 4.7L V8 - you gain 14 RWHP and 17 RWTQ over the factory exhaust manifolds.

 

Thats a decent gain, do you have a graph for the 5.7? It has a differnet factory manifold.

 

I agree, and no I have not seen a graph for JBA LTs on the 5.7L yet.

 

YEP^

 

Numbers are listed above. It's about 50hp.

I do NOT want a loud exhaust, nothing loud enough to block out the sounds the 5.7L engine makes.
What exhaust should I look at to go with a set of JBS long tubes?

 

I'd call Keith @dirtydeeds if I were you.

 

If you don't want a loud exhaust then I might stay away from long tubes. @dirtydeeds can customize the mufflers on the exhaust to exactly what you want. I have no drone but it's loud when I jump on her. The headers scream too and I love it!!

 

Thank you.

 

Thanks for the mentions guys. Anyone in need of help give a call. 760-877-4234. I’ll keep y’all straight so you’re puttin $ where it counts and not into anything that doesn’t help performance.

 

Anyone have any positive or negatives on the stainless works headers?
