Stainless Steel Shorty Headers for LS Swaps
Best for: Projects needing a compact header solution in tight engine bays. These universal LS swap headers accommodate many swap configurations, including square-body C10 options and mid-1990s to late-2000s GM trucks. They support 4.8L, 5.3L, 5.7L (LS1), 6.0L, and 6.2L engines, covering Gen 3 and Gen 4 LS motors. Not designed for vehicles that originally came with LS engines.
- Universal LS swap compatibility across several classic trucks and SUVs.
- Shorty design to clear steering columns, frames, and suspension in compact engine bays.
- Not a fit for LT-series engines from 2014 onward.
Caution: These headers are intended strictly for LS swap applications and may require additional matching components for particular vehicles. If your project started with a non-LS engine, verify fitment before ordering.
Aborvito LS Headers for Chevy/GMC LS Swaps
Best for: Builders seeking a robust stainless steel shorty header with a V-band collector for stable exhaust connections in various GM swap builds. Suitable for LS1, LS2, LS3, LS6, LS7 and related 4.8L–6.2L V8 engines, including C10, S10, Blazer, Jimmy, and Silverado swap projects.
- Made from T304 stainless with a polished finish for corrosion resistance.
- Shorty layout designed for tight engine bays and modern swap layouts.
- V-band 1-5/8 inch primary with a 2-1/2 inch collector for secure sealing.
Limitation: Some configurations may require minor clearancing or mounting adjustments depending on the specific vehicle frame and steering linkage.
LS Swap Exhaust Headers With MLS Copper Gaskets
Best for: LS swapers who prioritize long-term sealing durability and a compact shorty design. These headers include MLS steel gaskets with copper collector gaskets for a durable seal across repeated heat cycles. Intended for LS engine swap conversions rather than direct bolt-on replacements for factory exhausts.
- Compact shorty design tailored for limited engine bay clearance.
- 1-5/8 inch primary tubes and a 2-1/2 inch collector to balance flow and fit.
- Designed specifically for LS engine swaps, not for LT or factory LS configurations.
Note: This kit emphasizes a robust gasket upgrade to improve durability in performance swap builds.
LS Swap Exhaust Header 1-3/4″ for 1960-1998 C10 and Related Trucks
Best for: Classic GM trucks needing a full-length, long-tube feel with strong mid-to-high RPM power gains. This 1-3/4″ header offers full-length tubes, mandrel bends, and 304 stainless steel construction, suitable for LS1, LS2, LS3, LS6, and LS7 engines in 1960–1998 C10, C1500, Silverado, and Suburban swaps.
- Full-length pipe design to maximize mid-to-high rpm power gains.
- 1-3/4 inch primary tubes with a 3 inch collector for improved flow.
- Fully mandrel-bent 16-gauge 304 stainless steel construction.
Caution: Longer tubes can require more space in older trucks; verify available under-hood clearance before purchase.
DMANAUTO Shorty LS Swap Headers
Best for: Builders prioritizing a compact shorty header with a focus on GM classic car and truck swaps. The design features 1-5/8 inch primaries and a 2-1/2 inch collector, compatible with 4.8L, 5.3L, 6.0L, and 6.2L engines (LS family).
- Shorty header with V-band collector suitability for easier install and gasket sealing.
- LS1, LS2, LS3, LS6, and LSx family compatibility.
- Not designed for LS4 or some non-standard LS variants; intended for classic LS swaps.
Limitation: Some engine swaps may require additional clearance modification depending on vehicle frame and exhaust routing.
DMANAUTO LS Swap Long Tube Headers
Best for: Projects aiming for maximum high-RPM power in larger LS swap builds, including C10, C1500, Silverado, and Suburban vehicles. These long-tube headers are designed for LS1, LS2, LS3, LS6, and LS7 engines with 1-7/8 inch primaries and a 3 inch collector.
- 1-7/8 inch primaries for stronger top-end power development.
- 304 stainless steel polished finish for durability and corrosion resistance.
- Specifically suited to LS engines; may require more under-hood space compared to shorty designs.
Buying Guide
Key purchase considerations include fitment, space, and engine compatibility. When choosing, consider the vehicle type (classic truck, SUV, or S-series), the LS engine family in use, and how much under-hood clearance you have for headers and collectors. Shorty headers are generally best when space is tight, while long-tube designs offer potential power gains at higher RPMs but require more room. Stainless steel construction tends to offer better corrosion resistance and longevity, with V-band or copper/MLS gaskets improving sealing reliability over time. If you are swapping into a vehicle that did not originally have an LS engine, verify that the header kit is explicitly designed for swap applications and not for direct factory replacement.
FAQ
- What is the main difference between shorty and long-tube LS headers?
Shorty headers are compact and easier to fit in tight engine bays, while long-tube headers typically offer more power at higher RPMs but require more space. - Are stainless steel headers more durable than other materials?
Yes, stainless steel cores resist corrosion better and maintain performance under heat cycles. - Do these headers fit LT engines or only LS engines?
These options are designed for LS family engines and are not intended for LT-series engines. - Can I reuse factory gaskets with these headers?
It is best to use the included MLS or copper gaskets and replace any worn OEM gaskets to ensure a proper seal. - Is a V-band collector preferred for LS swaps?
V-band connections can simplify installation and provide a reliable seal for high-heat applications. - Do I need professional installation?
Some kits include all hardware and gaskets, but professional guidance is recommended for precise fitment and exhaust routing.
