Shorty Exhaust Header for Toyota Sequoia (2008-2014) 5.7L

High-Flow Shorty Exhaust Headers for 2008-2014 Toyota Sequoia (XK60)

What it Does: The shorty exhaust headers replace restrictive factory cast-iron exhaust manifolds on the 2008-2014 Toyota Sequoia to optimize exhaust scavenging, reduce backpressure, and improve low-to-mid range torque delivery.

The Stock Toyota Sequoia Manifold Restriction

Factory cast manifolds on the XK60 platform are engineered for compact packaging and cost rather than aerodynamic efficiency. The OEM units feature rough internal casting walls, abrupt angle transitions, and pinched runners that create localized backpressure zones. Subject to severe thermal cycling during towing or sustained hill climbs, these heavy cast units commonly suffer from warped mating surfaces, exhaust stud shear, and micro-cracking around the internal collector transitions, choking the natural scavenging efficiency of the 3UR-FE V8.

The Engineering Solution

Constructed from mandrel-bent 16-gauge (1.5mm) 304 stainless steel, these tubular shorty headers provide smooth, unrestricted flow dynamics through dedicated 1-5/8 in. (42mm) primaries merging into a 2-1/2 in. (64mm) collector. Each head flange is precision laser-cut to 3/8 in. (9.5mm) thickness and hydraulically flattened to maintain a reliable, leak-free seal across all exhaust ports. Complete TIG-welded construction eliminates structural weak points, providing high fatigue strength and corrosion resistance against severe heat soak without requiring custom exhaust modifications.

What's Included

• 2 Shorty exhaust headers (driver and passenger side)

Frequently Asked Questions & Fitment Warnings

Does this fit the XK60 Sequoia?

Yes, this is a direct fit for the 2008-2014 Toyota Sequoia equipped with the 5.7L 3UR-FE engine; it does not fit models equipped with the 4.6L or 4.7L V8 engines.

Are modifications required for the secondary air injection system?

No, these headers feature integrated secondary air injection ports and include dedicated port gaskets to retain full compatibility with the factory emissions configuration.

The Toyota Towing Caliber

Heavy-duty hauling and sustained highway grade climbing demand consistent thermal dissipation and uncompromised structural integrity. Upgrading your Sequoia to mandrel-bent 304 stainless steel tubular headers delivers lower EGTs, robust crack resistance, and dependable pulling performance under maximum gross vehicle weight.
