H, Y, X Pipe which do you prefer, assuming all piping is ideal.
Which would you prefer on a NA motor with light mods?
Why would you choose one over the others?
I ask because the Nismo comes with a H pipe and the cat back I am leaning towards has a Y pipe but I have the option of just getting the axle back and saving some money.
Thanks you in advance for all your thoughts, opinions, and information.
