RWA 1310-B1 Pro Four header thru fire wall design. Tube size 1 1/2″ to 1 5/8″ to a 3″ collect. The thru fire wall design was initially for tube chassis cars but have been run on production chassis cars with great success. The exhaust pipe runs through the driver compartment and exits the passenger side halfway up the door. The smaller tube design works great on mild race engines running on short tracks. Ceramic coating is available, please inquire.
