These precision shapes would be impossible to fabricate using traditional tubing, so 304 stainless steel investment casting is used to create a durable, high-flowing adapter that ensures optimal performance without restriction.
Cast Stainless Steel for Longevity
Unlike universal or low-quality adapters, the IE Y-Pipe is investment cast from premium 304 stainless steel. This manufacturing process ensures exceptional strength, dimensional accuracy, and a corrosion-resistant finish—providing long-lasting durability under extreme heat and pressure.
