Whats the difference in y-pipes?

RE: Whats the difference in y-pipes?
the pipe diameter is probably a little bigger, but also, where the second pipe joins the forst, is a lot smoother merge point. some y-pipes jsut have a normal pipe comeing from one end of the motor, and the other pipe is jsut welded in from a 90 degree angle so it creates turbulence. an aftermarket y-pipe joins the two pipes in teh same direction, so the airflow is a lot smoother, thereofr making more power.
