MBRP FS9CA460 4 Inch Turbo Downpipe for 2015-2016 Ford 6.7L Powerstroke

The MBRP FS9CA460 is a high-performance 4-inch turbo downpipe designed specifically for 2015-2016 Ford 6.7L Powerstroke diesel engines (non cab and chassis models). This Armor Plus Series component is engineered to maximize exhaust flow and reduce backpressure, delivering improved throttle response, enhanced turbo spool, and better overall engine performance.

Premium T409 Stainless Steel Construction:

Crafted from corrosion-resistant T409 stainless steel, this downpipe offers excellent durability and protection against penetrating rust. The T409 material provides a value-oriented solution that stands up to harsh conditions while remaining easy to clean and maintain. Each component is backed by MBRP's lifetime warranty, giving you confidence in long-term reliability.

Mandrel-Bent Design:

All tubing features precision mandrel bending, which maintains consistent pipe diameter throughout each bend without rippling or crimping. This manufacturing process ensures unrestricted exhaust flow, allowing your engine to expel spent gases more efficiently and draw in more fresh air for improved combustion and power production.

Key Features:

• 4-inch diameter for maximum flow capacity
• Smooth mandrel-bent tubing eliminates flow restrictions
• Bolt-on installation with factory mounting points
• Enhanced exhaust tone with aggressive diesel sound
• CARB compliant with EO number D-763-1
• Lifetime warranty coverage

This downpipe is an essential upgrade for Powerstroke owners seeking to unlock additional performance while maintaining emissions compliance. The CARB Executive Order (EO# D-763-1) certification ensures this component meets California emissions standards and is legal for street use in all 50 states.

Note: While T409 stainless steel resists penetrating rust, exposure to heavy winter conditions, salt air, or road treatments may accelerate surface corrosion. Complete part failure due to these conditions is covered under MBRP's manufacturer warranty.
