What You Get
Key Benefits
- 4-1 design improves exhaust scavenging and increases low to mid-range torque
- 1.76 inch primaries match the factory port size for direct fit without porting
- 2.89 inch collector outlet reduces back pressure and improves flow at high RPM
- Stainless steel construction resists rust and heat degradation over time
- Complete kit includes headers, gaskets, and hardware for a ready-to-weld installation
Why Buyers Switch
Problems It Solves
- Factory cast iron manifolds restrict exhaust flow and limit power gains at higher RPM
- Mild steel headers rust at the flange and collector within a few years of use
- Generic headers require cutting and welding to fit LS engines, increasing shop labour time
- Missing hardware in some kits forces buyers to source gaskets and bolts separately
Where It Is Used
Application Scenarios
- Performance shops building LS-based muscle cars and track machines
- Distributors stocking vehicle-specific headers for the 1997-2014 Chevrolet small block V8 market
- Tuning shops upgrading factory manifolds on Corvettes and Camaros for better throttle response
- Online sellers needing a vehicle-specific part with a clear fitment list and no generic claims
Buyers
Who It Is For
- Performance parts distributors buying LS engine headers by the pallet
- Diesel and truck accessory wholesalers serving the American muscle car market
- Independent installation shops that fabricate and weld exhaust systems on site

Comparison
Compared With The Alternatives
| Factory cast iron manifolds | Factory manifolds are heavier and restrict flow; these headers improve scavenging and increase torque |
|---|---|
| Mild steel headers | Mild steel is cheaper but rusts at the flange and collector; stainless steel lasts longer in harsh conditions |
| Universal headers | Universal headers require cutting and welding to fit LS engines; this kit bolts on with no modification |
Installation
Use Guide
- Confirm the engine is a 1997-2014 Chevrolet small block V8 with LS1/LS2/LS3/LS4/LS6/LSX engine
- Verify the intake manifold and port configuration matches the factory setup
- Remove the factory manifolds and clean the cylinder head ports before installing
- Use new gaskets and hardware from the kit to ensure a leak-free seal

Answers
Questions About This Part
Will this fit a 2005 LS6 Corvette with a modified intake?
Only if the intake manifold uses the standard factory port location. Modified intakes may not align with the header ports.
What is included in the kit?
One pair of headers, gaskets, and mounting hardware. No welding consumables or exhaust tips are included.
Is this a bolt-on installation?
No. Installation requires exhaust fabrication and welding. It is not a direct bolt-on replacement.
What material is used and why does it matter?
Stainless steel resists rust and heat cycling better than cast iron or mild steel, especially in high-temperature environments.
Can I use this on a 2000 Firebird with a 5.8L V8?
Yes, if the engine is the factory LS1/LS2/LS3/LS4/LS6/LSX variant. Confirm the engine code matches the fitment list.
Do you offer private label packaging?
Yes. Private label packaging and barcode labels can be arranged, and bulk cartons are available for container orders.
Is this street legal in my country?
We do not claim emissions compliance. Check your local regulations before resale or installation.
