How much HP can you get out of a mid muffler delete and a hellcat lower air box on a stock 6.4

[@TheDiamondProject]

that's considerably more than I anticipated seeing. I figured 7-10 on the air box and ducting. and 5 at best with mmd

[@JohnPartsDesigns]

Totally agree I was shocked

[@Alwayz_Angry]

Dropping the gems for the mod starter package guys!

I loved this short video. I wish more channels did this same exact thing

[@JohnPartsDesigns]

I’ll be doing a much longer video coming up. We are going to install a supercharger and do a before and after!

[@DesertRunner602]

@johnparts3405 Most channels do way more useless talking than showing the reason why we're watching the video. I loved this video because it was straight to the point. If these other channels can't stay on topic, then they should do quick videos like this one, in my opinion.

Nice

I like this channel 🤙

[@JohnPartsDesigns]

Thanks. Wanna help share it for me. I’ll keep putting out content as long as I can. I have a really big build coming too. So like and subscribe

[@aspman97]

Liked and sub'd, but a bit skeptical of the results.

[@MST8KS]

Stock scat filter before and after or with the hellcat filter?

[@JohnPartsDesigns]
