  • Spec-U Equal Length Headers

    URD is proud to announce our new Spec-U True Equal Length Long Tube Header for the 1GR-FE 4.0L V6 engine. We have tested different tube lengths in an effort to maximize the low end torque production without sacrificing the upper end power gains. The equal length design also improves the sound or tone of the exhaust.

Just a little out of the norm for a Monday at URD. This morning there was a house fire on the street behind our warehouse. The crew from URD responded to assist the local fire department. We have an all-volunteer fire service here.

As we got on the scene the crew from the first responding engine company rescued an unconscious female victim from the house and placed on the ground. Two people from the ambulance crew came over and there was no pulse or respiration. CPR was started and I ran back and forth to the ambulance to get the needed gear, O2, backboard, stretcher.

The ground was very soft from all the melting snow so she had to be carried to the ambulance. The good news is a pulse was restored on the scene, but the ambulance was stuck in the mud and a second unit was called in to transport her to a waiting helicopter.
