Engineered specifically for 2008 through 2010 Ford F-250, F-350, F-450, and F-550 Super Duty trucks powered by the 6.4L Powerstroke twin-turbo diesel engine, the aFe Twisted Steel Up-Pipe System (Part # 48-33016) provides a high-flow, durable replacement designed to withstand extreme thermal cycles without cracking or leaking soot.

Constructed from 100% TIG-welded mandrel-bent 304 stainless steel tubing paired with rugged flex joints, this standalone upgrade optimizes exhaust gas velocity and turbo response.

Key Features & Benefits

• Durable 304 Stainless Steel: Fabricated from mandrel-bent stainless steel tubing for ultimate corrosion and heat resistance.
• Heavy-Duty Flex Bellows: Equipped with internal liners to handle thermal expansion and prevent premature failure.
• Thick Laser-Cut Flanges: Features 0.375-inch thick flanges to ensure a tight, leak-free seal at the manifolds and turbo inlet.
• Improved Exhaust Velocity: Smooth interior bends reduce turbulence, lower EGTs, and accelerate turbo spool-up.
