Before 2 months I’ve installed this mods to my 5.7 charger

• mopar cold air intake
• 6.4 auto camshaft
• 6.4 headers
• mopar performance cat back
• custom dyno tune

And i got total 386 WHP while the base line was 353 with the mods and before the tune
And I bought a AFR long tube headers so im asking how much WHP the AFR LT will add ?

You will need the custom tune updated after installing the long tubes. I would ask the dyno tune shop what they predict the new RWHP will be. They know the current tune and how much extra they typically get from adding long tube headers.
.

Thanks 🙏 ,my car now at the garage for headers installing and after the tune I will give u an update ❤

Consider the 6.4 intake manifold. It will likely get you some power. Of course, anther tune to optimize it.

I got a nice 14 whp the tuner told me that I would get more if I changed my cold air intake to AFE
