What is the main benefit of a straight-through muffler design?

A straight-through muffler design allows exhaust gases to flow more freely through a perforated core. This typically results in a smoother, deeper exhaust tone and can contribute to improved engine performance compared to more restrictive muffler designs.

What materials is this Magnaflow muffler made from?

This Magnaflow muffler is constructed from 100% stainless steel. This material is chosen for its durability and resistance to corrosion, helping the muffler withstand the elements and last longer.

Can I install this muffler myself?

While this muffler is designed as a universal part, professional installation is highly recommended. Proper integration and welding into your existing exhaust system often require specialized tools and expertise to ensure a secure and leak-free fit.

About this part

Product Details

This Magnaflow muffler, part number 12398, gives you a 3-inch center inlet and dual 3-inch outlets, all housed within a 5x8x24 inch oval body. It's a straight-through design, meaning the exhaust gases flow directly through the perforated core, which is wrapped in stainless steel mesh and acoustic fiber fill. This construction is key to achieving that signature Magnaflow sound – a smooth, deep tone that's not overly aggressive, along with dyno-proven performance gains.

Built entirely from 100% stainless steel, this muffler is made to resist corrosion and last a long time. The straight-through layout is also bi-directional, so you can install it in either direction to best fit your exhaust system. While it's designed to be a universal fit, professional installation is recommended to ensure it's properly integrated and welded into your existing exhaust setup. The satin finish on the stainless steel body also adds a clean, finished look to your undercarriage.
