Do I need to remove anything to install this?

You'll need to unbolt the factory manifold and disconnect any sensors or brackets bolted to it. The new header uses the same mounting points, so no frame cutting or welding. Have a jack, socket set, and some patience ready.

Will this work with my stock exhaust?

The header outlet diameter isn't specified in the product data — test-fit your existing exhaust piping to the outlet flange before finalizing installation. You may need a transition piece or new piping if diameters don't match.

Do I need to tune or reprogram anything after installation?

No tuning required. If your factory oxygen sensors bolt to the manifold, they'll move to the header flanges. Keep the sensors and wiring intact during swap — no ECU reprogramming necessary.
