2011+ Challenger 6.4L Hemi Stage-2 NA Package Adds 50whp!

Love the overall driving experience of your stock 6.4L Hemi, but want just to hear and feel it more when you hit the skinny pedal? That's where our Stage-2 Naturally Aspirated package comes in!
This package delivers a significant increase in all the engine sounds you want more of, without any you don't (i.e., like annoying drone), topped off with up to an additional 50whp where you'll use it most in the powerband!
And the great part? When you're ready for even more, you're just our camshaft package away from making it Stage-3, without having to change any part you've already installed. It's no wonder this package is a favorite among our customers.

I'm pleased with the work, National Speed hooked up my ride...thanks to the management team and most important the mechanics. I'll be back for Stage 3 cam.

[@walt669]

My Dayton is there now I dropped off yesterday for the Stage 3 kit I'm so Excited

[@392CRO]

[@HollaIfYaHemi392]

​@walt669 how Lilong did it take you to get your vehicle back and if you did it from out of town did you have it shipped and if did what service

[@charlesseara8502]

Maximum horsepower point was gained simply by adjusting the SRV actuation up to somewhere between 4900 and 5100 rpm.

[@jr-fy7hh]

Hell yea currently own a 6speed 6.4 liter

[@compprufus]

Oh I love it. Everybody else here on yt are ripping stock exhaust system off making it absolutely unbearable, at least listening to the video with headphones. You did what I sought for such a long time, LT or ST with stock everything + cats. It does sounds betterer and yet doesn't piss off neigbours, cops and officials. By the way, how are the stock cats holding up with added power? Do they last less or would a larger/longer universal cat be vise to install regarding emissions?

[@lockdown_392]

These numbers are kinda high they baseline lower than this. What dyno are you guys using ?

[@johnlimpkin]

Mustang Dyno aka The Heartbreaker will take most people down to Earth lmao

[@roc-da-mike]

I have a 15 chal scat, be on the look out for me. My goal is stage 3 but i think im gonna start with stage 2. I live in Snow Hill, about 1.5 hrs from the Wilmington national speed!

[@michaellocklear640]

Cat's out of the bag, the stock catback is the best aftermarket system..

[@Chewie374]

I dont get the part when he said PCM unlock when your getting a tune. Why you have to take it out?

[@joellasierra]

Cause you can’t tune the pcm unless it gets unlocked

[@Srt_Kev]

What’s the SAE numbers witch is the true number

[@sepg5084]

True number lol 😂 Want true numbers? Go to a hub dyno.

[@Srt_Kev]

@@sepg5084 hub Dynos are one of the most accurate for sure

[@LoneStarSRT]

What camshaft do y’all think would be best for a intake and header only scatpack?

[@murdered300c]

FRP tuning has the fastest SBE 392 and they run their tomahawk cam

[@chetmanley610]

3 year olds know the number 30 and the number 50 aren't the same!

[@pwilliams3410]

You would think The work that was done to this car in the video it should already be pushing 500 horsepower

[@sepg5084]

Nope. 500whp is around 580hp at the crank. For a 6.4L that's 90hp/L. Can't do that with catalytic converters and stock cams.

[@Purpleppleater994]

id be more pleased if i could get a response...

[@FranciscoHernandez-dq7rf]

All that for just barely 500hp mmm bet it’s like close to 10k labor and parts mmm nah I’ll keep it 485 hp not really worth it imo.

[@ragingbull3406]

485 is advertised crank hp not at the wheel.

[@realitysux_0128]

Crank hp is different from wheel hp. The 485 is crank hp. Depending on the dyno, that’s between 410-420 at the wheels.

[@Ajay-rw5jy]

And it’s like 4k I think i was looking at the same package not bad considering they’re gonna tune the vehicle too #MoparNoCar

[@Chewie374]

You can install that by yourself. It's very easy.

[@joellasierra]

Thats like 516 crank horse power. It didnt break 500 at the wheels but it did at the crank.

[@FUBBA]

Awesome
