FAQ

Q: What horsepower range does the Viper PhatShaft 63 support?
A: It’s ideal for moderate fueling upgrades on 2nd-Gen 5.9L Cummins builds focused on towing and street performance.

Q: Do I need custom tuning?
A: Not strictly required for a basic bolt-on, but calibrated fueling helps spool and EGT control—especially with larger injectors.

Q: Will my stock downpipe work?
A: No. 2nd-Gen PhatShaft turbos use an HX40-style outlet and require a 4" HX40 downpipe (see recommended parts above).
