im going to be going turbo very soon. i have a itr and will be using a drag gen III kit. im going to run a .4 bar spring. i already have a 60mm catback system. should i just cut the piping and put a 3" or just leave it? thanks. Oh btw, i plan on just running only 240 hp for now until i rebuild my motor.
