What You Get
Key Benefits
- 1-7/8 inch primary tubes increase exhaust flow and reduce back pressure compared to the restrictive factory manifold
- Stainless steel construction resists rust and heat cycling better than cast iron or mild steel
- Gaskets and bolts included in the kit reduce installation time and prevent missing parts
Why Buyers Switch
Problems It Solves
- Factory cast iron manifolds crack under thermal stress and restrict exhaust flow
- Mild steel headers rust at the flange and fail after a few seasons in humid or salty climates
- Missing gaskets or bolts delay installation and lead to customer complaints
- Universal headers require cutting, welding, and custom fitting, which increases shop labour time

Comparison
Compared With The Alternatives
| Factory cast iron manifold | The stock manifold is heavier and restricts flow; this header improves exhaust velocity and engine response |
|---|---|
| Mild steel aftermarket header | Mild steel is cheaper but rusts at the flange; stainless steel holds up through repeated heat cycles |
| Universal header kit | A universal kit requires cutting and welding; this one bolts on directly with no modifications |
Installation
Use Guide
- Confirm the vehicle is a 2004-2007 Cadillac CTS-V with 5.7L or 6.0L V8 LS6 or LS2 engine
- Let the engine cool completely before removing the factory manifold
- Replace the factory gaskets with the new ones included in the kit
- Torque the flange bolts in a crisscross pattern to prevent warping
- Recheck bolt torque after the first heat cycle to ensure no leaks
