This is the Killer B Motorsport Tial MV-S Dump Tube. This dump tube has been designed to route the hot wastegate gases and discharge to the ground rather than having the wastegate dump the gases into the engine bay. This will work specifically with the Tial MV-S v-bad wastegate outlet, and it is the replacement component for the Killer B Holy Header with the EWG setup.
