My brother drives a SRT8 challenger with a MBRP exhaust and he says his will smoke mine?? could this be true he is the one that test drove it because he lives in LA so i kinda take his word but some how i doubt it!
Don't doubt it, it is 425 HP & most likely another 20 or more from exhaust.
More important: who gives a damn about few seconds off.
Kids today spend their life concerned about speed & 1000's are in cemeteries for it.
Just buy the car for the car & enjoy it, speed will get you nowhere but in trouble!
