American Racing Headers

Wow sucks that you had to go through all of that drama but at least now I know I’m not the only one that kinda stuff happens to lol. I’m curious if the smooth shifting you now get is commensurate with how it feels with the DAP tune? There’s considerable difference in how these trucks shift w/o it.

 

The DAP added 32. The headers added 40 in addition to the 32 for a total of 72!

 

Since he already modded his truck, I don't think we can do the math that easy. There are other factors starting to come into play. For example, injectors. He is moving a lot of air through the engine with the tune and air filter. Add the headers and it can really move a lot of air. But the injectors may not be able to keep up. That's just one.

By the numbers, this is likely turning about 490hp at the crank. 266/385=0.69. 69% of HP is reaching the ground. 338/.69=490hp. Now let's add the supercharger kit that comes with larger fuel pump and larger injectors. 600hp plus? That will shred a drive line and rear diff.

 

Now compare the cost for the tune with the cost including installation for everything else, the tune delivers the biggest bang for your buck - no contest.

 

That’s true. And so much less hassle. Those headers look difficult to install.

 

That's a wicked wide stance you have there, what are you running?

 

Than why the jba headers gain 49hp and 89lb torque with no tune. Dyno 367hp to the wheels and 375hp with tune.

 

At what cost installed?

 

Cost is not really the point here.

This thread is not " let's criticize the cost of this and that, as to belittle the OP's completely awesome exhaust and success.

Great system, if I wasn't supercharged, I would do this system too.

And I wouldn't be nickel and diming the project... As long as I was happy with the results, that's all that matters!

 

Dollars spent for ever HP gained should be considered & discussed, and nobody is criticizing / talking shit about the OP's exhaust.

 

It could range from 1000 to 2200 depending on the shop. I got a quote for 1400. Thats only installing long tubes and mid pipe connecting to my catback. Thats from CTM customs.

 

4000 for race exhaust. 7000 for supercharger. Let the install be out of the equation. Race exhaust with no tuning gains 49hp with jba headers similar to arh. Puts down 367hp to the rear wheels thats 433hp crank with 18% parasitical loss. Superchatger gets you 550hp thats roughly 451hp to the rear wheels. 49hp at 4000 is about $81 per hp. And supercharger at 169hp is $41 per hp.

 

You can't exempt the installation cost out of the equation, these mods don't make any power sitting in a box.

Does anyone know what the parasitical loss for the super charger is?

 

Mod for mod. But supercharger would bit a bit higher than longtubes if you dont have flex fuel. If you have flex fuel i would say a wash on installation than you dont need new fuel pump or injectors. Installation can differ alot. Maybe do it yourself and save like 1500.

 

Even with Flex fuel, you may wind up having to replace the fuel pump and injectors if you truck goes into limp mode all the time... Then you will have to have a custom tune made to account for the larger injectors and pump.
The fuel rail, pump, filter, and injectors from Pro Speed is almost $2300. labor and tune would likely be another $1500-2000
A flex fuel SC could cost $7000 + $2300, plus labor to install everything and to develop a custom tune. Could be at $12K all said and done.

A S/C used to be a mod I wanted, but I no longer want to deal with all the potential issues that a flex fuel engine entails.

 

ARH long tube direct connect headers are on my short list of future mods, and the approximate real world cost per HP gained after shipping and installation of this specific kit are factored in is about $110.00 ... DIY installation is not an option for me, and the SC is something I wanted - but no longer want.

 

Well to be honest i bought a tundra for reliability and most reliability problems are from sc tundra. I want to owned my truck for the next 7 years so im trying to think smart and go for long tubes and have one badass sounding tundra.

 

If you buy the mangson supercharger they come with injectors and fuel pump and bullydog tune for 7000. Install is going to vary on place but around here its about 1500 and if you want dap tune 600. 9100 all together for 169hp. It used to be 504hp but mangson bumped it up 50hp.

 

I can't argue with that... I am also trying to keep it simple & reliable.

 

Well with arh exhaust is 4000 and if you get dap tune 600. You gain 71hp and install average is 1500 so everything would be 6100 out the door. So it would be 85 per hp.

 

I picked up the DAP for $500 during a sale, the ARH system I am looking at is about $3100 installed and I already have a cat-back to connect it to, it was about $750 on sale. I realize my HP gain may not be as high as the full ARH kit, but I'll save about $2k.

 

Oh you bought the arh longtube and mid pipe. Did you add cats? Actually the h pipe that arh has is ok i rather perfer the x pipe is better with true duals will get you to that number for sure 3in all the way.

 

I haven't made my ARH purchase yet (I'm waiting for a sale), and the system I am looking at is their direct connect kit with cats. It connects directly to the factory exhaust... in my case it will connect to the BAMuffler exhaust cat-back with a stock single tail pipe I installed a couple of months ago. The headers are the only missing pieces in my HP puzzle.

 

Oh ok if you connect to the bamuffler with single exit you will be down some but its still going to be a big difference.

 

I've been trying to keep up with this thread a bit so don't blast me too much if I'm missing the obvious.

I am new to the Tundra world. I just bought a 2020 and preordered the Magnuson Supercharger. I rolled the SC into the loan with an installed price of $8,000. We are just waiting for Magnuson to finish their programming of the H-Key. It does include the Bully Dog tuner but I've hearing a lot about DAP tunes. Can someone advise or recommend where I can researched the benefits & difference between the Bully Dog and DAP tune?

Also, I do want to get an exhaust system either peice by peice or later all at once; in all honestly this is mostly for the sound. I've been looking at doing a JBA titanium ceramic headers ($650), BAMuffler 10" dual & TRD dual tailpipes combination. Having come across this thread, I liked the idea/sound of ARH full system but it seems that it may not be that beneficial, being supercharged. Does anyone have advise on ARH vs TRD dual vs the combination mentioned?

I did see mention of the added power shredding the drivetrain. I don't plan on going hard all of the time - just having some fun here and there - is this something that I should be concerned about?

 

Yes, that's the plan.

 

No need to add long tube headers. Dosent add any power really only lowers boost but will achieve the same hp. Supercharger will take it to 550 which to me is a shit ton!! Only problem you will have is not getting enough traction. But sc tundra does put a massive strain on everything. If looking to get 200,000 miles out of the truck that might not happen but you never know. All depends how you treat it. I think if you do your maintenance more frequent than usual you should be ok. Its just the 5.7 engine can handle so much until something breaks
600hp is the breaking point for these engines. If i was you i would do a bamuffler trd catback and leave everything else stock.

 

Do not do LT headers if you are supercharged. I talked to Kieth @dirtydeeds and he has the answers you are looking for. I had the TRD dual exhaust and supercharger. I stuck with the BD tune to keep it simple, I wasn't looking for anything beyond what they felt comfortable with. I swapped my TRD duals for the BAM TRD replacement system with the X-pipe and resonators. I get PLENTY of power when I need it and it sounds phenomenal. Don't drive like an idiot and you'll enjoy the setup for a long time. I also get 19mpg and have zero regrets.

I paid $8200 for the SC installed at my dealership and about a grand for the BAM exhaust.
BEST $10k ever spent.

 

I have 10 wides with 1.5" spacers runnin 35" rubber. I just bought another set of wheels that are 10 wide but 37" rubber that is 13.5 wide so I'll ditch the spacers but should look good.

 

Join the DAPtised Tundras FB group for plenty of posted dyno numbers on various pulls. You may have to scroll down a ways though - it's a pretty chatty bunch.

Hope you invested in a bulletproofed tranny. Several of the SC'ed Tundras I've come across have upgraded to L10 trannies and swapped gears. With headers, it's a no brainer.
