Dual Ported
What is the difference between Borla Dual Port and Single Port Headers other than the obvious?
Is there a benefit to one over the other? The dual port is cheaper, or very close in price, depending where you look.
If you go to Borla's website and choose a 1998 Subaru Impreza with a 2.2L engine, both come up as matching the car.
