Heavy-Duty 11-Gauge (3mm) Wall • Tight Radius • Turbo • Exhaust • Fabrication
PRODUCT OVERVIEW

The XS-POWER 4" to 3" 90° Cast Stainless Steel Reducer Elbow is engineered for fabricators who demand maximum durability, superior exhaust flow, and professional-quality construction.

Unlike thin-wall fabricated elbows, this premium reducer is manufactured from solid cast 304 stainless steel featuring an impressive 11-gauge (3mm) wall thickness, making it ideal for turbocharger manifolds, downpipes, exhaust fabrication, intercooler plumbing, and countless custom performance applications.

The smooth cast interior and precision 90-degree bend help minimize turbulence while maintaining consistent airflow through the transition from 4-inch O.D. to 3-inch O.D., resulting in improved flow characteristics and exceptional durability under extreme heat and pressure.

    ⭐⭐⭐⭐⭐ Built Like a Tank – Perfect for Custom Fabrication!

    Posted by Benji Contu on 1st Aug 2026

    ⭐⭐⭐⭐⭐ Built Like a Tank – Perfect for Custom Fabrication! I used this XS-POWER cast stainless reducer on a custom turbo exhaust project, and the quality exceeded my expectations. The 304 cast stainless steel construction is extremely heavy-duty, and the 3mm wall thickness gives you plenty of material for clean TIG welds without worrying about distortion. The transition from 4" to 3" is smooth, which helps maintain excellent exhaust flow, and the tight 90-degree radius worked perfectly in a tight engine bay. Unlike thin fabricated elbows, this casting feels incredibly solid and is built to handle high heat and high-boost applications. If you're building a turbo manifold, downpipe, or custom exhaust system and want a premium reducer that will last, this is an outstanding choice. Excellent machining, excellent material, and exactly what serious fabricators are looking for. Highly recommended! ⭐⭐⭐⭐⭐
