Unleash The Inner Beast

There’s a primal roar that every driving enthusiast craves from their car.

This authentic sound, coupled with great performance, truly defines a powerful driving experience. Not many cars exemplify this more than Honda’s FN2 Type R.

The right aftermarket exhaust system for the FN2 will not only make the hairs on your neck stand up as you reach 8000RPM, but will also noticeably improve performance from the K20 engine.

When it comes to exhaust upgrades, there are loads of different systems out there at different price points. Plus, it’s hard to know how an exhaust is going to sound and perform until you fit it. 

This guide aims to cover all the best and proven high quality exhaust systems available for the FN2 Type R so you can find one that fit’s your budget and needs.

Whether your priority is increased sound, maximum performance, or both – we’ve got you covered.

Before we take a look at the best individual products, we’ll touch quickly on a couple of key things to consider before investing in any exhaust upgrade.

Things To Consider

One of the main things to consider before purchasing an aftermarket exhaust system is what exactly it is you want from it. This may sound silly and obvious for many of you, but different parts of the exhaust affect performance and sound more than others.

For example, if it’s maximum performance you are after, then you may want to look into upgraded headers such as a 4-2-1 exhaust manifold to really improve exhaust gas flow. For best results, have your FN2 remapped after fitting this upgrade.

If it’s sound you are after, then you will want to replace the cat-back/backbox section of the exhaust which is responsible or muffling the sound coming from the tailpipes.

Another thing to consider if how loud you want the exhaust system to be. 

Inevitably, opting for a more free flowing exhaust even if it’s just for performance gains will lead to louder acoustics. While this may be desired, you may not want an exhaust that is too boomy for daily driving or one that puts you in the bad books with the neighbours.

If this is the case, try to keep the centre silencer (resonator) when upgrading the exhaust.

Now we’ve covered that, let’s now look at all the best options at your disposal.

We’ll start by looking at the upgrades that enhance performance the most then we’ll cover the upgrades to enhance that beautiful VTEC sound!

Japspeed 4-2-1 Exhaust Manifold

Starting at the performance end of the upgrades, a 4-2-1 exhaust manifold is one of the best valued modifications you can make for increased power on the FN2’s.

This exhaust manifold replaces the standard restrictive manifold, drastically improving exhaust gas flow.

With this upgrade, expect a much sharper throttle response as well as noticeable power gains.

It’s worth noting that these manifolds are sold for track use only, as they won’t pass emission tests such as an MOT.

Gravity 4-2-1 Exhaust Manifold

The Gravity exhaust manifold is another great upgrade to unlock additional power from your K20 engine, and comes in slightly more affordable for those on a budget.

Gravity are well known throughout the car community for their affordable and good quality exhaust systems for a variety of cars.

Similar to the previous Japspeed 4-2-1 manifold, this won’t pass emission tests so keep that in mind when buying it.

Regardless, it’s still one of the value mods for increasing power while keeping the car naturally aspirated.

Japspeed Decat Downpipe

As we work our way pass the exhaust headers, we come to the downpipe section. 

This affordable and simple upgrade from Japspeed replaces the restrictive standard downpipe with a free flowing catless variant.

Measuring at 2.5 inches, the width of the downpipe is increased and the lack of catalytic converter allows the exhaust gasses to flow more freely.

As with the previous manifold upgrades, this is sold for track use only and won’t pass emission tests. You could consider a high flow sports cat as a road legal alternative.

Scorpion Resonated Cat-Back

If you’re wanting a more meatier sound from the exhaust without it being too over the top, then the Scorpion resonated cat-back is for you. 

Unlike many exhaust systems, this one comes with a resonator (centre silencer). While the system does give you a lovely sporty growl, the resonator prevents it from being too overbearing.

This is a great choice if you have already upgraded the exhaust manifold or downpipe as a those upgrades increase the sound on their own as well.

Milltek Non Resonated Cat-Back

If you are wanting a proper aggressive sound from a high quality and respected exhaust manufacturer, then the Milltek non resonated cat-back is for you.

Unlike the previous Scorpion cat-back, this does away with the resonator so will be louder as a result.

Giving off a lovely sound when you pin the throttle, this free flowing cat-back can also slightly improve performance as well!

Cobra Non Resonated Cat-Back

We thought we would chuck another great option in if you are after increased sound.

Behold the Cobra non resonated cat-back system. 

Similar to the previous Milltek system, this exhaust upgrade is fantastic for those looking for a aggressive sound and an increase in performance.

The Verdict

We hope you found this guide useful at helping you decide which exhaust systems are best for your beloved FN2 Type R.

All the systems mentioned in this guide are a safe option if you are after performance and reliability, with them all coming from reputable brands.

As mentioned earlier, consider your goals.

If it’s performance you are after, purchase one of the 4-2-1 exhaust manifolds and then have the car remapped. You’ll be impressed!

Looking for some extra sound? For something subtle, chuck on a Scorpion resonated cat-back. For something a bit more loud and aggressive, opt for the Milltek or Cobra cat-back.

There’s no reason you can’t combine all these upgrades too. There is nothing stopping you from running an upgraded exhaust manifold and decat with a cat-back.

Happy modding!
