Im currently running a 95 200SX-SER. I have the JWF Header and Pop Charger, soon to be adding a cold air intake system to it. Im debating this possible setup for the exhaust. I will purchase a high flow cat, aftermarket resonator (Mine was taken off and can not be found), 2.25 piping from the cat back and finally a borla muffler. I am unsure if this will cause a dramatic loss in back pressure or if it will prove to be a good combo with my existing mods. Any feedback or possible ideas?
