Purchased a 2017 Scat pack for myself and cosigned for a 2017 SXT for my 24 year old son. For some reason I wind up with the SXT a lot of the time. Can't figure out why. lol My Scat pack is stock but I am wondering if the Hellcat intake is worth it. Does not have the Shaker hood. Also looking for other ideas. It's running 4.2-4.5 0-60 using 93 octane depending on traction and timing at launch The SXT has a K&N drop in, Magnaflow exhaust, and is using 89 octane. It is running steady 5.5's 0-60.
