- O2 sensor ports are pre-drilled and positioned to match factory sensor locations
- Long tube design maintains factory routing and fits under the vehicle without modifications
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 exhaust ports within a few seasons
- Universal headers require cutting, welding, and custom fitment, increasing shop labour time
- Incorrect fitment on non-SRT models leads to returns and customer complaints

- Bulk cartons provided for container orders instead of individual retail boxes
Comparison
Compared With The Alternatives
| Factory cast iron manifolds | Factory manifolds restrict exhaust flow and limit power gains; this header improves flow and increases performance |
|---|---|
| Universal cut-to-fit headers | Universal headers require welding and custom fitment; this one bolts on without modifications |
Installation
Use Guide
- Confirm the vehicle is a 2006-2018 Dodge Charger, Challenger, or 300C SRT8 with 5.7L, 6.1L, 6.2L, or 6.4L V8
- Do not install on non-SRT models or base trims as fitment will not match
- Replace factory gaskets and use new bolts to ensure a leak-free seal
- Torque flange bolts in a crisscross pattern to maintain flange flatness
- Recheck torque after the first heat cycle to prevent leaks
