Yes. The PhatShaft 62 is built to improve spool and lower EGTs with mild fueling upgrades, making it a strong towing and daily-driver choice on 2nd Gen Cummins trucks.
Do I need an HX40 downpipe?Yes. The PhatShaft 62 uses an HX40-style outlet. A 4" HX40 downpipe is required for proper fitment and exhaust sealing.
What supporting mods are recommended?At minimum, use a high-flow air filter/intake, free-flowing exhaust, and ensure your lift pump and fuel system are healthy. For higher power, consider upgraded injectors and tuning appropriate to your year/engine.
Is tuning required?Tuning isn't strictly required for basic operation, but proper calibration and fueling upgrades will maximize performance and keep EGTs in check.
Is this a direct bolt-on?It's a drop-in style turbo for 2nd Gen 5.9L Cummins, but you must use the HX40 downpipe. Some trucks may need a small tweak to the oil drain to clear the wastegate rod.
