What makes mandrel bent tubing better for an exhaust system?

Mandrel bending maintains the pipe's full internal diameter throughout the bend, unlike crush bending which can constrict the pipe. This smoother, consistent diameter allows exhaust gases to flow more freely, potentially improving performance and sound.

What is included in this 10-pack?

This product includes ten individual universal exhaust pipes, each with a 4-inch diameter and a 45-degree bend. They are made from stainless steel and are intended for custom exhaust fabrication.

Are these pipes ready for direct installation on any vehicle?

No, these are universal components designed for custom exhaust systems. They will likely require cutting and welding to be integrated into your vehicle's specific exhaust layout. Always refer to manufacturer instructions for proper installation procedures.

Product Details

Starting with a 4-inch diameter, this Magnaflow exhaust pipe is built with durable, corrosion-resistant stainless steel, making it a solid choice for custom exhaust projects. The 45-degree bend is precisely formed using CNC robotic manufacturing, ensuring consistent angles and smooth transitions for better exhaust flow. This ten-pack of pipes is designed to simplify the process of building or repairing a custom exhaust system, offering a well-made component that stands up to the elements.

The mandrel-bent tubing is a key feature here. Unlike crush bends that can restrict flow, mandrel bending maintains the pipe's full diameter throughout the curve. This means your exhaust gases can move more freely, which can lead to improved performance and a deeper exhaust tone. Magnaflow backs these pipes with a limited lifetime warranty, giving you confidence in their longevity for your build.

Because these are universal components, they are ideal for fabricators and DIYers looking to create a unique exhaust setup or replace sections of an existing system. While they are not CARB approved and cannot be shipped to California, they offer a robust solution for many other custom exhaust applications. You'll want to plan your layout carefully, as these are designed for custom fitments and may require cutting and welding to integrate into your specific vehicle's exhaust.
