Product Description

The MBRP FS9455 is an XP Series turbo down pipe built for the 2008-2010 Ford F-250/F-350/F-450 6.4L Powerstroke, replacing the restrictive factory unit with 4-inch, 16-gauge T409 stainless steel construction. Where the stock downpipe uses a restrictive 3-inch ID dual-wall design, this pipe significantly opens up exhaust flow, letting the turbo breathe more freely for lower exhaust gas temperatures and real power gains.

Owners can expect up to 40rwhp gains along with quicker throttle response, all from a straightforward 2-piece design that bolts directly to the OEM catalytic converter and DPF for a hassle-free upgrade. T409 stainless steel construction delivers strong corrosion resistance and long-term durability under the heat and stress of turbo diesel exhaust temperatures.

Backed by MBRP's Lifetime Warranty on 409 stainless steel construction. Note that removing OEM catalytic converters may violate emissions laws depending on your jurisdiction, and this part is not for sale or use in California.
