Before you order: fitment and what to plan

The exhaust manifold or header collects exhaust from each cylinder and sends it into the exhaust system.

Fitment notes

  • Drivetrain: AWD. AWD and 4WD versions often use different parts from 2WD versions of the same car.
  • Engine: check the engine size listed against your vehicle's VIN or under-hood label.
  • Specs, lead time and warranty come from Bull Boost and can change. The details above this guide are the latest we have.
