Headers on a 5.7 Hemi Charger Challenger 300. Worth it? Dyno results + insights

The 5.7 Hemi is an excellent platform to build on folks.

The 5.7 is a great engine , the problem is that it's stifled from the factory through the throttle body , the intake , the exhaust manifold and the cats . Take care of those issues and a tune , You'll have a nice running 5.7 ! Add a head and cam package and You can play with scats ! My last MOPAR was a 2020 scatpack shaker , and I would by an R/T in a Heartbeat !

[@ReidPerformance]

Totally agree! You're spot on with the factory restrictions on the 5.7 Hemi.

Not sure how you only picked up 6 peak whp going from that rich to what I assume you left it at which is around 12.8(.88).

Great video brother. Wish you were in Texas! Just got a ‘23 RT Blacktop and am very pleased with the way this 5.7 drives and feels. Perfect blend of muscle, fun & comfort. Really, really want to do headers, CAI and tune. Questions Did a mid muffler delete. If I do headers, CAI & Tune would I be ok just leaving the mid muffler delete or would a performance exhaust like Borla ATAK or Corsa extreme be better for the mods I mention above. Also. How how you counseled guys like me who are scared to do these mods because warranty will be out the window. Thanks

You can keep mpg the same with a tune. In my opinion, mid muff delete is sufficient. My personal scat has headers, high flow cats and no mid mufflers and it is the perfect sound. Loud and deep, but not obnoxious and there is no drone

How much hp do you think a 5.7 5 speed would make if it had 1 7/8th bbk headers and a 6.4 cam? And is it worth it to even upgrade the 5.7 if there is the 6.4? I have a 5.7 and I havnt upgraded anything in a while bc it feels pointless sometimes to be upgrading this car that only got 290-330 whp.
