first off please excuse my ignorance, but im just starting the exhaust on the cuda and im not sure what size pipes to use? its got the 235 hp 273 with mild work done to it. the manifolds flange is, to my measurement, 2 1/8"? correct me if I am wrong. im also probably going to be straight piping the car. thanks ahead of time.
