What makes mandrel bent tubing better than crush bent tubing?

Mandrel bending maintains the pipe's full internal diameter through the bend, preventing restrictions. Crush bending, on the other hand, can flatten and narrow the pipe's opening, which can impede exhaust flow and reduce performance.

What does 'universal' mean for these exhaust pipes?

Universal components are not made for a specific vehicle model. They are designed to be cut, fitted, and welded into custom exhaust systems. You'll need to determine how to integrate them into your vehicle's exhaust layout.

What is the warranty on these Magnaflow exhaust pipes?

These Magnaflow exhaust pipes are backed by the manufacturer's limited lifetime warranty, which covers defects in materials and workmanship.

Product Details

Magnaflow offers these universal exhaust pipes to help make custom exhaust setups easier to build and ensure they last. This particular pipe is a 90-degree bend with a 4-inch diameter, made from durable stainless steel. It's designed to help you create smoother transitions in your exhaust system, which can lead to improved flow and performance. Magnaflow uses CNC precision robotic manufacturing techniques for consistent quality, and these pipes are mandrel bent. Mandrel bending means the pipe maintains its full diameter through the bend, unlike crush bends which can restrict flow. This attention to detail helps ensure dyno-proven performance gains. These pipes come with Magnaflow's limited lifetime warranty, giving you confidence in their longevity.

Because these are universal components, they are intended for custom exhaust applications. You'll want to plan your exhaust layout carefully to integrate these pipes effectively. The stainless steel construction means you don't have to worry as much about corrosion, especially if you're building a system for a vehicle that sees regular use in various weather conditions. This 10-pack gives you multiple pieces to work with for more complex custom builds or for having spares on hand.
