The Silver 64 is great for the daily driver / tow vehicle, The Silver 66 works well for a street performance truck who tows light loads, and the Silver 69 is designed for the ultimate street performance truck and weekend warrior! Just like all of our Silver Series Turbos they come standard with a 14 cm exhaust housing in which we modify the angle of the exhaust nozzle, maximize the wastegate ports, and enlarge the wastegate chamber for full wastegate travel, dual grooved high performance bearings and an adjustable boost elbow.
