In this article, we’ll review some of the best aftermarket exhaust systems for the Scion FR-S.

Review of Top-Rated Exhaust Systems for FR-S:

1. Borla 140496 – Best Exhaust System for Scion FRS

The Borla 140496 exhaust system will definitely change the sound of your FR-S and provide a minimal performance increase. It isn’t the appropriate exhaust system for the performance enthusiasts, nor the loudest Borla exhaust system for the FR-S, but it’s also affordable.

If you’re willing to sacrifice both sound and performance for a more reasonable price, then the Borla 140496 is a great choice. This budget-friendly exhaust system will increase engine performance by 4 to 6 horsepower and torque at 4700 RPM. Not the greatest boost, but, again, this exhaust system isn’t as expensive as other Borlas.

This exhaust system is 25% lighter than the stock exhaust system on the FR-S and is a good option if you’re trying to reduce the overall weight of your car. It has an aggressive sound without being super loud. Don’t be mistaken, though: it is louder than the stock exhaust system.

Overall it’s a good system. It offers a small performance increase, better sound over the stock exhaust system, and improved fuel economy without breaking the bank.

2. MagnaFlow 15157 – Best Sounding Exhaust System for Scion FRS

MagnaFlow doesn’t make claims regarding performance increases with the 15157 exhaust system, and they shouldn’t. As a matter of fact, if there are any performance increases with this exhaust system, then they are minimal.

This is another system that focuses on sound and sound quality. The MagnaFlow 15157 produces a deep, rich tone that can get loud but isn’t overly boisterous. People will notice your FR-S and complement its sound without being annoyed by it. As we all know, when it comes to exhaust sounds it’s easy to overdo it and this MagnaFlow exhaust prevents any exaggerations.

Although the rumble is pleasing, it has a negative: there’s a high chance you’ll encounter drone (even if minimal) at higher RPMs. We found the drone to be bearable, but you should be cautious because it might be a dealbreaker.

3. CORSA 14864BLK – Stainless Steel Exhaust for FRS

Corsa Sport always produces great exhaust systems, regardless of the vehicle. The 148654 is no exception.

Sure, it might not be the best system if you’re looking for increased performance, but it is a strong contender in the sound side of things. Corsa offers 4 sound levels, from an unnoticeable rumble to a menacing growl.

The best part is that despite how noisy it gets, due to Corsa patented technology, there is absolutely no drone with this exhaust system. It does get loud, so don’t be surprised if your neighbors complain. If you find this system to be too boisterous you can always get one of the quieter options.

There’s some performance increase, as alway, but this one is for the sound aficionados and a great buy overall.

4. Invidia HS12SSTGTP – FRS Cat Back Exhaust

This Invidia exhaust system will greatly increase engine airflow. It boosts the overall performance of the vehicle, even if Invidia is shy to share some approximate numbers.

We found that this exhaust system strikes a good balance between sound and performance. Sure, it’s not a significant increase, but it is noticeable at higher RPMs. You’ll have a stronger top-end with this system, both horsepower and torque wise.

The sound is not overly menacing. It has a deep rumble that is pleasing to the ear, both inside and outside the vehicle. You shouldn’t expect any drone with this exhaust system.

---

5. Invidia R400 – Exhaust System for Scion FRS with Titanium Tips

Again, Invidia makes no claims about performance improvement with this exhaust system. We didn’t find any either.

Although this is not a bad system, others are better (both quality and price-wise) for your FR-S. Even Invidia has better exhaust systems for the Scion FR-S.

Like with the J2 exhaust, we advise you to buy this system if it is the only possibility of upgrading from the stock exhaust system. It has a deep, aggressive tone, but other exhaust systems also bring that to the table.

---

6. Auto Dynasty AD-J2-CBE-003 – 2.75′ FRS Exhaust

Although this is a good exhaust system, there probably are better options for your FR-S First of all, J2 claims this system offers up to 10% gains in both horsepower and torque (15 to 25 hp). However, multiple consumers haven’t found that to be the case. Sound-wise it’s a bit muddy, even though it’s loud.

No products found.

On the plus side, this exhaust system is not too expensive. Yet, when you consider the competition, it isn’t a system to seriously consider unless you get a major deal on it.

The performance increases are minimal and the sound is dislikable. It’s better than the stock exhaust system and if it’s your only aftermarket stock option then definitely upgrade to it,but you would be better off with some other exhaust systems on our list.

7. Perrin Performance PSP-EXT-360BR – Best 2.5′ Exhaust System for Scion FRS

Perrin Performance’s exhaust systems don’t always improve the efficiency of your vehicle. If you are not familiar with the brand you might suppose that this exhaust system’s name is “Performance PSP-EXT-360BR” and take a few things for granted. No, this is not a performance exhaust.

Although Perrin Performance claims this system will increase the power of your vehicle, they don’t share any approximate figures.

Of course, any proper aftermarket exhaust system should always improve the performance of a vehicle one way or another. A good exhaust system will increase engine airflow and more airflow equals more combustion (which leads to better functioning). Such is the case with the PSP-EXT-360BR.

If you’re looking for an exhaust system that will impact the performance of your car, then this one might not be for you.

Lovers of loud cars will not find joy in this exhaust system either. This one is for the FR-S owner who likes to keep things mellow and simple. This system does have an impact on the sound of the car, but instead of making it louder, the PSP-EXT-360BR softens the tone and is ideal for those who live in a residential area.

This Perrin Performance exhaust system is mellow and not aggressive. Luckily, there’s something for everyone out there.

8. Agency Power AP-FRS-170 – Scion FRS 13-16 Exhaust

The Agency Power AP-FRS-170 greatly increases engine airflow and has an impact on the performance. However, Agency Power refuses to give out an estimate.

There’s little doubt about it, yetIt would be nice to have an estimate, for a change. The large pipes offer excellent airflow and reduce the backpressure, which results in more horsepower and torque. Still, you’ll have to run a few tests to learn the exact figures.

No products found.

This exhaust system has a nice finish and is expected to outlast the vehicle itself. Its sound is not too pronounced, but a definite upgrade over the stock exhaust system. It is not the system if you’re looking for something loud.

Exhaust For FR-S — Buyer’s Guide

Scion FR-S, Toyota 86, Subaru BRZ

Back in 2003, Toyota wanted to appeal to a younger audience with sleek and fast cars. As the Toyota name was already well known and not entirely targeted at their new intended market segment, they created a new brand, Scion.

The Scion FR-S was released in 2012, and although it was discontinued after 2016, the truth is Scion was reabsorbed by Toyota. The FR-S didn’t stop being produced, it just reversed to its name outside of the US: Toyota 86. A GT version, the Toyota GT86 is also available, which features some upgrades over the base version.

The Toyota 86 and the Scion FR-S are similar. Their only difference is the brand, explained by Toyota’s attempt at targeting a younger audience.

Then there’s also the Subaru BRZ. The Subaru BRZ is akin to the Scion FR-S (or Toyota 86). On the outside, few things set both cars apart. They’re manufactured in the same place but have a different grill and headlight placement, among other small alterations. Both vehicles also slightly differ on the inside. The BRZ has a unique suspension setup and interior.

Despite the differences between the BRZ and the FR-S, since both cars are almost exactly alike, exhaust modifications are compatible with both vehicles (provided they were manufactured in the same year). FR-S and BRZ mods are almost always compatible.

Are ARK Performance exhausts good for the FR-S?

ARK Performance exhausts are very good and you should have no problems using them in the FRS. As with most premium aftermarket exhaust systems, and ARK Performance will increase the efficiency on your FRS.

Since most aftermarket exhausts increase engine airflow, they also increase the overall engine performance. More air in the engine means higher combustion, which means more horsepower and more torque.

Can every FR-S exhaust fit any year FR-S?

No. Newer FR-S exhaust systems will not fit older Scion FR-S vehicles. The spacing of holes varies between model years.

If you’re thinking about buying a used aftermarket exhaust system for your FR-S, make sure it fits your vehicle. If you’ve already bought it and are just finding out it doesn’t fit, you can always modify and align it yourself, but the hassle is probably not worth it.

Remember to buy an exhaust system appropriate for your vehicle (make, model, and year) or you’ll have many unwarranted headaches.

How to remove the FR-S exhaust system?

If you’re keen on fixing your car maintenance and dislike visiting shops unless necessary, then you might want to replace the exhaust system. Changing an exhaust isn’t very difficult. It all begins with removing the stock system.

Here’s how to remove the stock exhaust system from the Scion FR-S:

1. Remove the two spring bolts in the flange connection of the catalyst while supporting it with a jack stand.
2. Separate the rubber grommet from the hanger. If you’re having trouble separating these two parts, use a soap and water solution.
3. Remove the muffler hangers from the grommets on the driver’s side. Support the driver’s side exhaust system with a jack stand and remove the ones on the passenger’s side.
4. Remove the stock exhaust system from the vehicle.

Then, depending on which aftermarket exhaust system you’re installing, you might want to remove the graphite donut gasket on the flange. Don’t forget to read the instruction booklet on the newly bought exhaust system to confirm if it’s a necessary step.

How to install the FR-S exhaust system?

After removing the stock exhaust, installing a new one is a matter of doing everything in reverse.

To install a new exhaust system on your Scion FR-S do the following:

1. Place the gasket against the flange while having the stock pipe protruding through it and insert a bolt through the flange, gasket, muffler assembly, washer and place a nut at the end.
2. Place the axle pipe hanger into the rubber grommet.
3. Align the muffler inlet expansion with the outlet of the axle pipe and slide it over.
4. Insert the hangers into the rubber grommets in both the driver and the passenger’s side.

Make sure that everything is snug and fit, and you’re done.

How to tune exhaust headers on FR-S?

There’s no need to tune the exhaust headers on the FR-S. Catback exhaust headers need not be tuned and cat (or no cat) headers aren’t legal.

How to fix crooked exhaust tips on FR-S?

On rare occasions, hitting a bump or a curb might crook your exhaust tip. Fortunately, fixing a crooked exhaust tip is relatively simple if you’re using an aftermarket system.
It’s also simple if you’re still using the stock exhaust system, but it has an extra step along the way.

In most vehicles, exhaust tips are bolted on. The exhaust tips on the FRS are no exception. Fixing a crooked exhaust tip is as simple as loosening the bolt and rearranging the tip until it is no longer crooked. Then you just tighten the bolt again and the exhaust tip is no longer crooked.

Sometimes, the Scion FR-S exhaust tip bolt is protected by a small tack weld. If that’s the case with your FR-S then remove the tack weld to get to the bolt.

After removing the tack weld, loosen the bolt and put the exhaust tip back into place. Tighten the bolt and you’re done. If it ever happens again you will know how to fix it.

Frs muffler delete – will I have drone?

Yes. One of the main disadvantages of deleting the exhaust is the quantity of drone. Although some prefer the muffler deleted sound of the vehicle, not everyone can support the drone.

Is it possible to have a single exhaust on the FR-S?

Yes, it is. There are single exhaust systems available for the FR-S. However it will look different from a typical FRS, since it has two exhausts. On the plus side the entire vehicle will be lighter and have a simpler system.

What size are the FR-S exhaust bolts?

The FRS uses 14mm bolts on the stock hardware.

Frs exhaust parts

The FR-S exhaust system has the same parts as any other. Exhaust systems are composed of the manifold, the catalytic converter and the muffler.

Is the Scion FR-S stock exhaust good?

The Scion FR-S stock exhaust is okay. Most stock systems bring nothing new to the table. You can’t talk about performance improvements since the baseline is measured using the stock exhaust system.

The only thing worth mentioning is the sound: the FR-S stock exhaust is loud, but not overly so. If you’re looking for a menacing tone, then there’s definitely room for improvement.

An aftermarket exhaust system is always a good option because it allows you to change the sound of the car to one more of your liking and it can increase the overall performance of the vehicle.

Some exhaust systems, besides improving the performance of the car, also improve its fuel[note]https://www.nap.edu/read/12924/chapter/4[/note] economy.

The bottom line: there’s nothing wrong with the Scion FR-S stock exhaust, but you should definitely change it if you have the means. After all, upgrading from the stock exhaust will only improve your vehicle.

Should I change the header when doing an exhaust change on the FRS?

Depending on the reasons why you’re performing a replacement, then you might want to change the headers as well.

Exhaust system upgrades can impact the sound and the performance of your vehicle. If you’re upgrading to get a better sound, then you can forget about changing the headers. However, if what you’re interested in is an improvement in performance, then changing the headers is advisable.

As a matter of fact, headers usually have a way bigger impact in performance than the rest of the exhaust system.

Thus, if it’s power that you’re after, upgrading the headers should be a no-brainer.

What does a resonator do in an exhaust system?

The resonator, sometimes also referred to as a pre-muffler, functions as a chamber that accumulates the sound from the engine and readies it to be silenced by the muffler.

Albeit, it does not operate as simply as that. Although the main function of the resonator is always the same, resonators are acoustically engineered for the vehicles in which they are installed. This ensures the resonator is in tune with the engine, resulting in a pleasant sound for the driver.

What are some good exhaust mods for the FRS?

If you’re planning on modifying the exhaust, the best mod is a Catback system. Check our list above If you’re looking for the best exhaust system for the FR-S.
