hi there i have a JDM s15 with standard turbo and 3" exhaust from the dump back.
i am looking at picking up an aftermarket dump pipe but not sure what design to go, either the open 3" pipe or the split style that splits off the wastegate gasses.
i have read a few debates for this so wondering what you guys think?
