The FK8 is the first Civic Type R to come to the states, and it’s without a doubt the best Civic Type R ever. Not only is it significantly more powerful than any other Civic Type R before it, but the chassis is exceptionally well balanced, and the brakes are pretty good. It’s arguably the best front-wheel-drive car ever produced. Enthusiasts know that even the best cars in the world can always be improved upon. One of the first modifications many FK8 owners choose is an aftermarket exhaust. Not only is it an easy way to pick up some power, but it also adds some much-needed sound to the driving experience.
As you might expect, there are quite a few exhaust systems for the FK8 on the market and choosing the right one can be tough. For this reason, we’ve compiled a short list of what we believe are the best FK8 exhaust systems. This list is in no particular order. All of these exhausts have their pros and cons compared to each other.
Coming in around $1300 – $2000 depending on the configuration, Milltek’s cat-back for the FK8 isn’t particularly expensive but also isn’t some fantastic deal. The price is very middle of the road, the but quality is excellent. The entire system is made from high-quality aircraft-grade 304 stainless steel. This material is anti-magnetic and is less susceptible to discoloration. Unfortunately, Milltek does not offer a valved version of this exhaust which saves weight but means you need to choose the resonator options wisely.
There are three different version available: a fully resonated version which is comparable to the stock exhaust, a partially resonated version which is noticeably louder than stock but still relativity quiet, and a non-resonated version which is very loud and sounds incredible. Tips are available in Burnt Titanium, Carbon Jet, Cerakote Black, Polished, and Titanium. Also available are downpipes with or without de-cat. De-cat models are only for race/track use and are not legal on the street.
Next up on our list is Remus. This is on the higher end of the exhaust systems listed in this article, but the quality is excellent as you would expect from a Remus exhaust. With this exhaust system, you can expect to gain around 6.9 horsepower and 9.8 Nm of torque. One of the best parts of this exhaust system is how it integrates with the onboard electronics. No vehicle modifications are required and can easily be installed without cutting the stock exhaust, 100% bolt on.
There are five tip options available ranging from 98mm to 102mm. The optional sound controller allows you to control the exhaust valves with a remote or phone application. With the exhaust, tips, and sound controller this exhaust comes in around $2000 – $3000 depending on the configuration.
Armytrix Valvetronic Cat-Back
If you want the loudest and best sounding valved exhaust possible, Armytrix is the way to go. Depending on the tips you choose, an Armytrix FK8 exhaust will come in around $2000 – $3000. Power gains are higher than average at +10 horsepower and +9 Nm of torque. This is thanks to the very smooth and streamlined designed. Unlike the Remus exhaust listed above, this Armytrix exhaust includes everything you need including the remote kit.
With the Armytrix exhaust, you have four different tip options to choose from: chrome, burnt titanium, matte black, and carbon. Available separately from the cat-back is a “race pipe” (de-cat) which is designed strictly for track and off-road use and is not road legal. The race pipe is available in a ceramic coated and standard finish depending on your needs.
Greddy is one of those companies who offers a plethora of products which are slightly different from each other. For the FK8, they offer two different catbacks: Supreme SP and HG Supreme. The HG stands for “High Grade” since that system uses premium metals and overall higher quality construction. Both systems use a similar design with 3” piping and stainless steel construction. The big difference is the tips. The Supreme SP uses a dual tip design which is different than the standard triple tip design, and the HG Supreme SP uses a triple tip design with one large tip in the center and two smaller tips on each side of the big tip.
The Supreme SP comes in around $700 which makes it the cheapest option on this list and the HG Supreme SP comes in around $1,500 which is an excellent price for the quality and crazy triple muffler design.
For the FK8 owners who need the lightest possible exhaust to help shed time at the track, look no further than J’s Racing. Although this exhaust is the most expensive on the list by far, costing over $5,000, it’s without a doubt made from the nicest materials compared to all the other exhausts. The entire system is made from titanium which is the reason for this massive jump in cost, but it’s also part of the reason this exhaust is so light.
Unlike the other exhausts which are made from standard exhaust piping and have a few mufflers or resonators, the J’s Racing exhaust is super thin titanium with as few mufflers and resonators as possible. Throughout the entire system, there is only one silencer. The result is the light FK8 CTR exhaust on the market. Because of the lightweight and loud nature of this exhaust, it is not approved for road use.
Next on our list is the Invidia R400 exhaust. A neat feature of this Invidia exhaust is the use of three independent mufflers/resonators. Most FK8 CTR exhaust systems use one or two mufflers/resonators, but the usage of three small independent units (one for each tip) should theoretically lower the weight of the exhaust, as well as add a uniquely deep exhaust tone. The system is built from stainless steel to help keep cost down, and the tips are made from titanium with a burnt-blue finish.
Even with that unique and complicated triple muffler setup, this exhaust is on the lower end of the price spectrum coming in around $1,200 or less. Unlike some other exhausts on the market, Invidia is offering this exhaust with a front pipe with eliminates the area where the exhaust decreases in diameter, which improves overall flow, resulting in more power.
