- ExclusionDoes not fit turbocharged models or vehicles with factory catalytic converters in the manifold
What You Get
Key Benefits
- 1-7/8 inch primary tubes improve exhaust flow compared to the restrictive factory manifold
- 201 stainless steel resists rust and heat cycling better than cast iron or mild steel
- Complete kit includes gaskets and hardware for a bolt-on installation without welding
Why Buyers Switch
Problems It Solves
- Factory exhaust manifolds restrict flow and cause high exhaust gas temperatures under load
- Cast iron manifolds crack or warp after repeated heat cycles, especially in high-mileage vehicles
- Poorly machined flanges leak at the cylinder head joint, causing loss of power and noise
- Universal headers require cutting and welding, which increases labour cost and reduces shop margins
Where It Is Used
Application Scenarios
- Performance shops upgrading 2005-2010 Cobalt and HHR models for improved throttle response
- Distributors stocking vehicle-specific headers for the 2005-2010 Cobalt and HHR market
- Online sellers needing a photographed, fitment-verified part with a clean listing
- Tuning shops installing headers on non-turbo 2.2L and 2.0L Cobalt and HHR engines
Buyers
Who It Is For
- Performance parts distributors buying Cobalt and HHR hard parts by the pallet
- Independent installation shops that require bolt-on headers with minimal prep
- Truck accessory wholesalers serving North American compact car owners
Construction
Technical Features

Comparison
Compared With The Alternatives
| Factory exhaust manifold | The stock manifold is designed for emissions compliance and lower noise, this header improves flow and engine response at the cost of increased sound |
|---|---|
| Cast iron aftermarket header | Cast iron is cheaper but cracks under heat cycling; 201 stainless holds up through repeated thermal stress |
| Universal cut-to-fit header | A universal header requires custom cutting and welding, this one bolts on directly with no shop labour |
Installation
Use Guide
- Confirm the vehicle is a 2005-2010 Cobalt or HHR with 2.2L or 2.0L engine and not turbocharged
- Let the engine cool completely before removing the factory manifold
- Replace the factory gaskets rather than reusing them to prevent leaks
- Torque the flange bolts evenly in a cross pattern to maintain sealing face flatness
- Recheck flange torque after the first heat cycle to ensure no creep
