Exhaust systems are a great aftermarket add-on that can transform your ride. Large pipe diameters, performance mufflers, and precise bends lead to increased horsepower and more aggressive exhaust tones. The brand of aftermarket exhaust system you choose may differ greatly as each manufacturer strives for a different sound. Two of the most popular aftermarket exhaust system manufacturers, Magnaflow and Flowmaster, are highly sought after due to their distinct designs and sounds. In this guide, we'll examine the details of both manufacturers' exhaust systems to help you determine which brand is best for your ride.

If you have questions about exhaust systems, mufflers, or any other exhaust components, chat in or call our product experts at 877-216-5446.

Magnaflow Exhaust Systems

Magnaflow carries a wide series of exhaust systems to accommodate daily drivers, off-road vehicles, racing vehicles, and more. Most Magnaflow exhaust systems are categorized according to the driving style or configuration of the vehicle in question.

When choosing a Magnaflow exhaust system, you will sometimes be prompted to choose which exit style you prefer. Choose rear exit if you want the exhaust to terminate at your rear bumper, or side exit if you prefer it exit from the side of your vehicle.

Performance Series.

Performance Series

Also known as the MF series, this exhaust system is designed to create a balance of interior resonance and exterior sound. This efficient design creates a slightly more aggressive tone than OE exhaust systems.

  1. Sound: Mild to moderate
  2. Construction: Stainless steel
  3. Warranty: Lifetime
Off-Road Pro

Off-Road Pro

Ideal for a truck that will spend most of its time on tracks and trails, the Off-Road Pro series is lighter than other designs. It is also designed to increased ground clearance and to accommodate modified suspensions.

  1. Sound: Moderate
  2. Construction: Stainless steel
  3. Warranty: Lifetime
Competition Series.

Competition Series

This design incorporates elements intended to maximize power and exterior noise: larger pipe diameter and a straight-through muffler design. The results, while impressive, are so loud and aggressive that they may not comply with local or even federal noise requirements. For this reason, this system is recommended strictly for racing applications.

  1. Sound: Aggressive
  2. Construction: Stainless steel
  3. Warranty: Lifetime
Rock Crawler.

Rock Crawler

This series is mostly found for Jeep Wranglers. It's designed to accommodate aftermarket rear bumpers and provides maximum ground clearance for vehicles that will see extreme off-road conditions.

  1. Sound: Aggressive
  2. Construction: Stainless steel
  3. Warranty: Lifetime
DPF Series.

DPF Series

The DPF series is designed for vehicles equipped with diesel engines and extends from the diesel particulate filter. It features intercooled tips to reduce exhaust gas temperatures. It is available in stainless steel, black powder-coated steel, and aluminized steel.

  1. Sound: Aggressive
  2. Construction: Stainless steel, black, or aluminized steel.
  3. Warranty: Lifetime (stainless, black), one year (aluminized).

Flowmaster Exhaust Systems

While Magnaflow categorizes its exhaust systems according to utility, Flowmaster arranges its exhausts according to the level of sound and power they create. This is mostly accomplished by using increasingly aggressive mufflers and larger pipe diameters.

Flowmaster often includes exit pipes for both rear and side exhaust configurations in its kits. This allows you to try out both styles and decide which you prefer during installation.

Force II.

Force II

Flowmaster's introductory exhaust system, the Force II system features the chambered 70 Series muffler with Delta Flow technology. If you're looking for a mild exhaust upgrade that isn't overwhelming, the Force II makes a great choice.

  2. Construction: Stainless steel
  3. Warranty: Lifetime
American Thunder.

FlowFX

The American Thunder system features a very aggressive exhaust note but maintains street-legal status in most areas. Comes with the Delta Flow Super 40 Series muffler.

  2. Construction: Stainless steel
  3. Warranty: Lifetime
Outlaw Series.

Outlaw Series

Flowmaster's most aggressive exhaust system, the Outlaw Series may not comply with local or federal noise ordinances. It includes the single chamber Super 10 Series muffler, which is only slightly quieter than running with no muffler at all.

  2. Construction: Stainless steel
  3. Warranty: Lifetime
