Magnaflow Smooth Trans 180D 4.00 SS 10pk 10712

If you're building a custom exhaust system or replacing a section of your existing one, these universal exhaust pipes from Magnaflow are a solid choice. This particular set includes ten 4-inch diameter pipes, each featuring a 180-degree bend designed to help you navigate tight spaces or create specific flow paths in your exhaust setup. They're made from durable stainless steel, which is great for resisting corrosion and ensuring your custom work holds up over time.

What sets these pipes apart is how they're made. Magnaflow uses CNC precision robotic manufacturing for consistent results, and the tubing itself is mandrel bent. This means the pipe's diameter stays the same throughout the bend, unlike crush bends that can restrict exhaust flow. This smooth transition is key for maintaining performance, especially in custom applications where every bit of flow matters. The dyno-proven performance aspect means they've tested these designs to ensure they contribute positively to your exhaust system's efficiency.

This is a 10-pack of pipes, so it's ideal if you're tackling a larger project or if you're a shop that frequently works on custom exhaust builds. Remember that these are universal components, so you'll need to ensure they fit your specific vehicle's needs and that they comply with local emissions regulations, as they are not CARB approved and cannot be shipped to California.
