Certified Automotive Experts Stainless Steel Shorty Headers for LS Swaps — Universal Gen III/IV Fit, Compact Installation Kit

These shorty-style stainless steel headers from Certified Automotive Experts are a universal, swap-only solution engineered to route exhaust cleanly for Gen III/IV LS engines during engine swaps.

Designed specifically for LS swap projects (not for vehicles that originally came with LS-style engines), these shorty headers simplify installations by offering a compact profile, stainless-steel durability, and a hardware kit that includes gaskets and bolts. They accommodate a wide range of popular LS displacements and popular vehicle swap platforms, making them a practical choice when retrofitting modern V8 power into older trucks and SUVs.

Will these headers fit my LS swap project?

These headers are built to accept most Gen III and Gen IV LS engines (1998–2020) including 4.8L, 5.3L, 5.7L (LS1), 6.0L and 6.2L variants. They are not compatible with LT-series engines introduced around 2014 and later.

• Compatible with LS1, LS2, LS3, LS6, LS7 and many other Gen III/IV engines
• Intended exclusively for vehicles undergoing an LS swap — not for factory LS-equipped cars
• Fits common swap platforms such as older C/K pickup generations and SUVs

How does the shorty design help during installation?

The shorty profile reduces the need for extensive frame or firewall modification because it tucks the collector and primary tubes close to the block. That compact layout speeds installation and gives more room for steering and suspension components.

• Lower-profile primaries clear tight engine bays and crossmembers
• Includes gaskets and mounting hardware for a straightforward DIY fit
• Shorter tubes make alignment and bolt-up easier during swaps

What materials and build details should I expect?

Constructed from corrosion-resistant stainless steel, these headers are made to withstand heat and road conditions while retaining strength and appearance. The flanges and welds are engineered for durability in high-temperature exhaust environments encountered during daily driving and spirited use.

• Stainless steel construction resists rust and pitting
• Welded collectors and reinforced flanges for long-term reliability
• Supplied with exhaust gaskets and bolts to prevent leaks at installation

What vehicles are commonly paired with these headers?

These headers are popular choices for classic trucks and SUVs being retrofitted with LS engines. They are used across a wide variety of swap builds where the goal is to add modern V8 power without extensive frame surgery.

• 73–87 and 67–72 C10/C20/C30 pickup swaps
• K-series trucks and K5 Blazer projects
• Suburban (73–91), OBS (88–99) C1500, Silverado, Sierra and S10 swap applications

Who is this for: If you're performing an LS engine swap into an older pickup, SUV, or custom project and need a compact, durable exhaust header that simplifies routing and installation, these Certified Automotive Experts shorty stainless steel headers are built for that purpose. They suit DIY mechanics, professional swap shops, and builders seeking a universal, swap-only header that fits many Gen III/IV LS engine configurations. Avoid these if your vehicle originally left the factory with an LS-style engine or if you require LT-series compatibility.
