The stock Y pipe has flow impediments. It has many bends and pinches down to some very small cross-sections. The stock Y-Pipe also poses a clearance issue some have run into – literally.

URD CNC machines our flanges to accept our collector crush gaskets that are included.  Our gaskets are specially made so they will not blow out with high exhaust pressure and heat even with our Supercharger Kit.  The rear flange is designed to accept the Toyota OEM donut style gasket.

The flanges have recesses machined into them that are the perfect depth for the gaskets.  The URD gaskets crushing O-Ring type gaskets.  When the bolts are tightened down all the way so the flanges come together, the gasket crushes just enough for a perfect seal.  With the flanges firmly flat against each other they don’t move, and they don’t bend causing leaks like some aftermarket exhaust systems and headers do.

The piping is 2.25” high quality, heavy gauge 304 stainless that is extremely durable utilizing only TIG welds and 316 welding rod. This Y pipe will outlast the vehicle.

The URD off road Y Pipe was designed for off road use and competition events.   The URD off road Y Pipe is not for on road use and is absolutely not emissions legal anywhere on public roads.

The URD off road Y Pipe does include ports for the rear O2 sensors.  We also include and extra O2 bung for easy installation of an aftermarket wideband display sensor.

Note- Not compatible with sub-frame type lifts that lower the front differential. The change in the angle of the front propeller shaft causes and interference problem.
