Are Aftermarket Exhausts Even Worth It? (Toyota GR Supra Edition)

Almost all of the generation of Supras have been great platforms for modifications. From the MK3 up to the MK5, the Toyota Supra has proven itself a great car to tinker with and modify. One of the most popular and banger mods car enthusiasts usually get aftermarket exhaust systems.

These mods are great because they come with a lot of benefits in tow. But ultimately, gearheads want these mods because they’re the key to making their cars sound very good.

However, you might be asking yourself: “Are aftermarket exhausts even worth the trouble, especially for my brand new Supra?” If you’re a bit skeptical, allow us to give you a quick rundown of the benefits you and your Supra can enjoy.

  1. Increased power output

Aftermarket exhaust systems add up a little bit of power to your vehicle. It may not be as much when compared to the 300+ horsepower output of the latest Toyota GR Supra, but it’s still enough to make a bit of a difference.

Aftermarket exhaust systems may even reduce your Supra’s backpressure (but not eliminate it).

  1. Better MPGs

The 2020 Toyota GR Supra A90 had an EPA rating of 24 mpg in the city and 31 mpg on the highway, respectively. However, the 2021 model suffered a loss of -2 mpg while in the city and -1 mpg while on the road.

Getting your hands on a high-quality performance exhaust system will improve your fuel economy by 2-10% and solve the mentioned fuel economy problem . It may not be that much, but in these modern times, every drop of fuel counts.

  1. Better Sound Output

This benefit is the most common reason why car enthusiasts get aftermarket exhaust systems. As car guys and gals, we have to admit that we get eargasm whenever we hear a car with some top-tier exhaust note.

Car enthusiasts have their exhaust sound preferences though. Some like to keep it chill, relaxed, and as moderate as possible. Others, however, prefer a loud and very aggressive exhaust tone, which is great either way.

Aftermarket exhaust systems are also great for cars like the Toyota GR Supra that have different driving modes. In these driving modes, you’ll have a better grasp of how the sound of your vehicle dramatically improves once it gets aftermarket exhausts.

Ultimately, exhaust systems give you the freedom to express your octane-fueled enthusiasm with nice-sounding cars.


In a nutshell, aftermarket performance exhaust systems add value (not monetary) to the car by improving its sound output, fuel economy, and performance.

When choosing an exhaust system for a vehicle like the Toyota GR Supra A90, you’re often left with various sound output choices: from moderate to very aggressive.

Most aftermarket exhaust systems also offer innovative features which allow the driver to have a better driving experience with the car. 

The list above featured the best exhaust systems you can find for your fifth-generation Toyota Supra. We hope that we’ve helped you in your journey of finding the best exhaust system to fit into your Toyota GR Supra A90.
