For those who want the best of both worlds of having the power and reliability increases that Pacific Performance Engineering's Race High Flow Exhaust Manifolds and Up-Pipes produce, yet retain the stock EGR system, PPE has an industry first: its optional Y-Pipe.
Made from 11-gauge .120-inch wall stainless steel and featuring an aircraft-grade bellows, these Y-pipes are designed to the same exacting standards as its regular Up-Pipe, but with an ad-ditional section that completes the connection to the EGR cooler.
Designed for the 2001-12 GM Duramax 6.6L engines, the Y-Pipe give you quicker engine warm-up and it enables the cab heater to function properly.
