This is a must have product for the 5.7 Naturally Aspirated OR Supercharged Tundra.
When URD put its supercharged 5.7 Tundra on the Dynojet with Thorley 5.7 long tube headers, it beat the wheel horsepower and wheel torque numbers of a manual Dodge 8.4 liter (SRT10) 600+ crank hp 10 cylinder. (Viper engine)
These numbers make sense since URD\’ Tundra walks away from STIs and the like to right past 115mph. Trust us, you want these headers.
