sweet, yea i think im gonna invest in a delete pipe to take off the dpf. i put the half exhuast on today and it didnt really do much. but i hope i can tune the pipe with the edge programmer i already got. how do you tell if its a race version or not. they both look the same to me

 

Dodge comes with 4 inch, but 5 inch full pipe, pulled dpf, pulled cat, kicks butt and fuel mileage almost doubled and efficency of the motor is great.
