Shorty Exhaust Header for Chevrolet Blazer Tahoe GMC Yukon (1992-1995) 5.7L

High-Flow Shorty Exhaust Headers for 1992-1995 Chevrolet Blazer, Tahoe & GMC Yukon (GMT400)

What it Does: The Shorty Exhaust Header set replaces the restrictive factory cast-iron manifolds on 1992-1995 Chevrolet and GMC trucks to minimize exhaust backpressure and optimize low-end torque delivery.

The Stock Chevrolet,GMC Blazer,Tahoe,Yukon Exhaust Manifold Restriction

Factory cast-iron exhaust manifolds on GMT400 SUVs equipped with the 5.7L L05 TBI Small Block Chevy feature pinched runner designs, rough internal scale, and severe cylinder-to-cylinder turbulence. These cast log-style configurations impede hot gas evacuation, inducing significant exhaust backpressure, high under-hood heat soak, and reduced volumetric efficiency under heavy towing loads.

The Engineering Solution

Fabricated from 16-gauge (1.5mm) mandrel-bent 304 stainless steel, these short-tube headers employ smooth 1-1/2-inch primary tubes merging into a high-velocity 2-5/8-inch collector. Heavy-duty 7/16-inch (11.5mm) laser-cut head flanges are hydraulic-press flattened to prevent exhaust gas leakage and thermal warping across repeated heat cycles. Every joint is precision TIG-welded for maximum structural durability while retaining stock flange locations for direct bolt-on fitment.

What's Included
