Top 5 Best Exhausts for the BMW F80 M3 and F82 M4

Back in 2014, at the North American International Auto Show (NAIAS), the new BMW M3 officially premiered. At the same time, the first BMW M4 hit the spotlight with the German marque separating the Coupe and Convertible from the Sedan. Technically, there was a further innovation in the BMW F80 M3 and F82 M4: for the first time in the series’ history, there was a turbocharger under the muscular hood with the inline six-cylinder engine (S55B30). The goal was to combine the benefits of a high-performance, naturally aspirated motor with the strengths associated with modern turbo technology. 

Even with an impressive factory output of 431 horsepower and 406 pound-feet of torque, many owners itch to squeeze out even more power from the engine. After all, factory exhaust systems are designed to maximize horsepower while keeping engine noise to a tolerable level. While this is acceptable for the average consumer, it leaves much to be desired in the hands of the automotive enthusiast. For those dedicated to unlocking the potential performance and excitement in their BMW, a powerful and loud aftermarket exhaust system can make all the difference. The following is a list of the top 5 best exhaust options for the BMW F80 M3 and F82 M4 based on their power gains, exhaust notes, aesthetics, and overall construction. 

1. VR Performance Titanium Exhaust System

The VR Performance Titanium Exhaust for the BMW F80 M3 and F82 M4 was born from precision structural and sound engineering. It was built specifically for these models to deliver increased sound and performance that will get you noticed as you zip by. Crafted from authentic high-quality titanium, this pie-cut system with mandrel-bent tubing combines the best of enhanced performance, unmatched exhaust tone, and a solid overall construction that is made to last.

This exhaust has been tuned to perfection and designed to elevate your BMW M3 or M4 to the next level with incredible sound and styling. The VR Performance exhaust produces a refined sound output that encompasses the sporty note of the S55B30 engine that can be found under the hood. Thanks to the Valvetronic design, you can change your M3 or M4 exhaust note with just the push of a button to switch between mild and wild modes. Best of all, this is a complete bolt-on exhaust that directly fits in place of the factory one without any cutting or welding needed.

The VR Performance system features a true dual 2.5-inch diameter and 0.4mm thick piping to ensure optimal airflow without sacrificing weight. The mandrel-bent and pie-cut titanium construction of this system allow for a “best of both worlds” situation for any BMW enthusiast as you reap the benefits of the advanced build without having to worry about any excess stress or weight to the vehicle. In fact, this system weighs in at just 51 pounds – that’s super lightweight compared to stock! At the rear, this exhaust features quad 3-inch burnt titanium tips to give the back end a more customized and sporty appeal that shows you mean business.


  • Total weight is 51.05 pounds
  • Super lightweight compared to stock
  • Delivers a fantastic exhaust note
  • Increases horsepower and torque
  • Features Valvetronic functionality
  • 2.5-inch Diameter, 0.4mm thick piping

2. Eisenmann Axleback Exhaust w/ Signature Tips

Eisenmann’s Stuttgart-based engineers are responsible for designing the OEM systems found on Porsche and AMG cars. They use this exact experience to design some of the greatest performance exhaust systems in the world. Eisenmann exhausts are built by hand from start to finish to create old-world craftsmanship that is simply unmatched on the automotive aftermarket. That being said, the Eisenmann Axleback Exhaust with Signature Tips will not only add attractive styling to your M-powered vehicle, but also deliver unparalleled performance, power gains, and overall premium construction that other competitors simply cannot match up to.

The construction of nearly all Eisenmann exhaust systems, both externally and internally, is made up of 100 percent lightweight, high-grade T304/T306 stainless steel throughout. Not only that, but its engineers paid specific attention to factors like wall thickness to create the best balance of reduced weight and an amazing sound. The canisters are machine-pressed into a shape specifically designed for the F8X M cars using a series of deep draw dies, which results in extremely high rigidity and contributes to that iconic Eisenmann tone. The canister shape was strategically created to completely eliminate the canisters from the rear view of the car, drastically improving the appearance of the BMW F80 M3 and F82 M4 models.

If you are looking for a premier exhaust manufactured by a brand that has leveraged over 30 years of heritage, Eisenmann is the brand for you. The design of each system from the tube configuration and the size of the muffler and box dimensions are meticulously calculated and optimized to provide maximum performance across the entire rev range, drawing on Eisenmann’s vast Motorsport experience. Multiple internal flow paths work together with BMW’s Sport, Comfort, and Sports Plus ECU programming, and enable Eisenmann’s valve control to have a variable and drastic effect on the exhaust’s personality. This works to yield a quiet tone during cruising with in-cabin comfort, as well as a full-on growl when you truly step on the gas.


  • Lightweight, high-strength construction
  • Signature exhaust tips for added styling
  • Quad 90mm round exhaust tips (4x90mm)
  • Max horsepower and torque gains in all driving conditions
