A 4 inch exhaust that replaces everything from the diesel particulate filter back, exiting out one side ahead of the rear wheel and finishing in a polished 5 inch stainless tip. The tubing is aluminized steel, which is the budget material in the MBRP range.
why this one — The cheapest F-450-listed exhaust on this platform at a regular 524.99 dollars, and MBRP Tour profile is their quiet tune, which matters on a truck you drive to work every day rather than to a show. Two honest catches. Aluminized steel will surface rust where the T409 stainless systems will not, so it is a value buy and not a lifetime one. And MBRP warns on its own page that trucks carrying a 35 inch spare may need the spare relocated to clear it.
MBRP publishes no horsepower claim for this system.
