Speed Engineering headers are made out of 304 stainless steel and offer great quality, performance, and affordability. Our headers are mandrel bent, tig welded, and feature natural stainless steel construction. All of our headers have been dyno proven. We stand behind our headers in saying you will not find a better fitting, quality built, budget header for your vehicle.

Note: Headers are natural stainless steel and X-Pipes are polished stainless steel on our first batch. Future batches will be all natural stainless finish.

  2. Great product and very happy with them. I will say the dipstick needs some customization for it to fit after these are installed but with an extra set of hands you do not need to remove the spark plugs. We did remove the steering shaft for the drivers side to make it easier but might not have been totally necessary. Highly recommend!
