ok so i already have a jba shorty header and i want to upgrade my exhaust cause im goin to get a supercharger down the road. what i was wondering is if i get a rt cat and 2.5 inch flex pipe and a borla exhaust and put it on before i get the supercharger, if it will affect my performance because the size of the pipe. cause its going to be alot bigger pipe with not a lot of flow going through it.
thanks,
kyle
