Notes
This complete header kit makes huge increases in the power output of your V8 Grand Cherokee. They are also fantastic option when replacing the crack-prone factory manifolds, rather than heading to your local dealership. The kit includes ceramic coated long tube tri-y headers and a complete performance y-pipe kit routing exhaust gases all the way to your exhaust system. Install these headers today and feel your vehicle's true power potential!
