Performance Exhaust Manifold for GMC Sonoma 94-04

Product Introduction

This stainless steel exhaust manifold is engineered as a high-performance replacement for the factory manifold on 1994–2004 Chevrolet S10 and GMC Sonoma pickup trucks. Designed to improve exhaust flow and reduce backpressure, this header is ideal for workshops and distributors looking to provide reliable, performance-grade solutions for light truck upgrades. The product supports 2.2L and 4.3L engine models, offering compatibility with both two-wheel and four-wheel drive configurations.

Made from high-grade 304 stainless steel, the manifold resists rust and cracking under high temperatures and vibration. The flanges are CNC-machined to ensure perfect alignment during installation. Welded using TIG techniques, the manifold delivers leak-free performance over time, even under harsh working conditions. This is an excellent upgrade for mechanics, performance shops, and commercial fleet maintainers who value durability and consistent performance.

Applications

The stainless steel exhaust manifold is widely used in aftermarket upgrade and maintenance scenarios. It serves as an ideal part for automotive repair shops replacing worn-out factory manifolds or enhancing the performance of light-duty trucks. The product is also suitable for vehicle customization services offering clients improved horsepower and torque through exhaust system upgrades.

Fleet operators maintaining multiple S10 or Sonoma vehicles can benefit from the improved efficiency and reduced maintenance frequency this manifold provides. For international buyers and bulk distributors, this item fits neatly into truck upgrade kits and is frequently ordered as part of a complete exhaust system solution.

Features & Benefits

Engineered with mandrel-bent primary tubes and precisely cut flanges, the exhaust header maximizes exhaust scavenging, supporting noticeable gains in engine performance. Each unit is carefully welded by skilled technicians to ensure high structural integrity. The thick flanges prevent warping during heat cycles, a common problem with cheaper alternatives.

The use of corrosion-resistant 304 stainless steel ensures extended service life even in high-humidity or road-salt environments. Whether installed in performance builds or daily work trucks, this manifold delivers consistent performance without frequent replacements.

From a business standpoint, the product's compatibility with two popular mid-size pickup models over a ten-year production span (1994–2004) ensures a broad application range and high customer demand. For importers and wholesalers, its compact packaging and durability make it ideal for international shipments.
