Unlock Performance with the PHR 4" Stainless Mandrel-Bent Downpipe

When it comes to pushing the limits of your 2JZ engine, every component counts. At Powerhouse Racing, we’ve engineered the perfect upgrade to maximize the potential of your turbocharged setup: the PHR 4" Stainless Mandrel-Bent Downpipe. Precision-engineered for an exact fit, this downpipe isn’t just a performance boost — it’s custom-built for your specific turbo and manifold, delivering the results your build deserves.

Tailored for Your Turbo

Unlike one-size-fits-all solutions, the PHR downpipe is built to fit your turbo perfectly. Whether you’re running a Precision, Garrett, Turbosmart, or Borg Warner turbo, we’ve got you covered. Our expert team builds each downpipe to order, using your manifold and turbo setup to ensure a seamless fit. This personalized approach eliminates guesswork and minimizes installation headaches, allowing you to focus on what really matters: getting the most out of your turbocharged beast.

Hand TIG Welding for Unmatched Quality

Every PHR downpipe is hand TIG welded by our talented fabrication team, ensuring precision and durability in each weld. For added strength and reliability, our welds undergo backpurging, which provides cleaner, stronger welds that can withstand the high heat and stress of turbocharged applications. This attention to detail ensures that your downpipe is built to last, giving you peace of mind with every mile.

Maximize Exhaust Flow

The key to turbo efficiency is optimizing exhaust flow, and that’s exactly what our 4" mandrel-bent downpipe does. With its smooth, mandrel-bent construction, it maintains consistent diameter throughout, reducing backpressure and improving exhaust velocity. The result? Faster turbo spool, better throttle response, and increased power.

Durability that Lasts

Built from high-grade stainless steel, the PHR downpipe is designed to endure the high heat and stress of turbocharged applications. Its corrosion-resistant properties ensure that it will stand the test of time, making it a dependable upgrade for your 2JZ engine for years to come.
