Upgraded Bellowed Up-Pipe Kit - 7.3 Powerstroke (L99-03)
Features & Details: Bolt on replacement Eliminates factory gasket Bellowed design - allows for expansion and contraction Description: This Bellowed up pipe kit for your 1999.5-2003 Ford 7.3 Powerstroke is the fix for the common issue that robs power from your engine. Due to expansion and contraction, and extreme heat cycles, the factory installed "donut" gasket designed to seal your factory up pipes will begin to leak over time. When this happens, engine power can be reduced drastically. These upgraded up pipes eliminate the the troublesome "donut" gaskets and replace them with durable steel crush gaskets that will not blow out or leak over time. The up-pipes feature a bellowed design that allows for expansion and contraction without need to rely on a factory gasket. **DOES NOT FIT e99 trucks. **
