I don’t think it’ll affect it at all, just gives it abit more volume before the blower. The MMX bypass is a brand new thing and probably isn’t on their website but is on Facebook (that’s where I saw it). They showed it as part of their Hellcat blower swap to a 6.4 kit
Not brand new, Whipple uses them.
I mean it’s a new kit for MMX specifically for the Hellcat, I realize they’ve been used forever (Eaton used them way back in the 90’s and maybe even before that)
