Dyno results for my ‘15 challenger rt 5.7 manual. Catless Borla XR-1 longtube headers, mid muffler delete , flow master super 10’s in rear. DSS 1-pc driveshaft, subframe lockout, P4Dvelopment full diff brace. Numbers definitely seem a bit high to me. No way I dyno’d 366 stock(had longtubes on and CAI installed on stock tune) I’ve regularly seen these dyno around 340 stock and then 360-375 with a tune(catless LTH,CAI). 395 seems unrealistic lol.
