Description

The RiffRaff Bellowed Up-Pipe Kit is engineered to replace the leak-prone "donut" gasket found in the 94-Early 99 Ford Powerstroke 7.3L engine. By eliminating the "donut" gasket and incorporating a bellow, these up-pipes ensure that all of your turbo's boost is utilized effectively, contributing to improved engine performance. The kit includes the 321 stainless up-pipes, stainless gaskets, and an OE install hardware kit, providing everything needed for the replacement. It is crucial to note that this kit is specifically designed for Early 1999 models and will not fit L99-2003 models. The product listing also indicates options for various configurations, including considerations for High Output (HO) motors, with potential add-ons such as an "Install Kit" or "Crankcase Oil Separator Filter." Buyers should verify their specific engine configuration to ensure proper fitment and select any necessary additional components.
