This MBRP exhaust system is great for Ford van owners from 2004 - 2007 with 6.0L engines. It's perfect for those living in dry areas or on a budget. You can use it during daily commuting, long - distance driving, or just to make your vehicle sound cooler. The exhaust has a 4 - inch cat - back single - side exit design, and the heavy - gauge aluminized steel tubing gives it good durability.
