BLITZ NUR Spec

[rudee023]

Has anyone installed a BLITZ NUR spec exhaust on their S13 KA24E/D? I am interested in modding my car with parts that I will end up being able to keep if I end up going SR later on down the line. My question is although with a turbo the bigger the exhaust the better, will the 80mm piping with an NA motor cause me to lose a significant amount of low end power due to the loss of backpressure?
