Description
This Product has been Discontinued
Fits: 2003-2007 Ford F-Series w/ 6.0L Powerstroke
The high-flow Sinister Ceramic & Heat Wrapped Exhaust Headers have been made to reduce under-hood temperatures and increase exhaust flow! On a stock tune, these headers have added 27HP/56 lb-ft of torque. Then on a modified tune, they have added as much as 37HP/99lb-ft of torque. These headers make a perfect upgrade for towing applications since most of the power is produced in the low RPM power band!
