If you're a Gen 2 Turbo owner, you're probably looking to upgrade your downpipe to squeeze out some extra power. The Gen 2 Turbo downpipe is a bit more complex than its predecessor, requiring some specialized tools and a bit more know-how.
The Gen 2 Turbo downpipe is a single-unit design, meaning it's a single piece that includes the downpipe, catalytic converter, and exhaust gases. This design makes it easier to install and replace than the Gen 1 Turbo downpipe.
The most important thing to consider when installing a downpipe on your Gen 2 Turbo is the flange type. The Gen 2 Turbo downpipe uses a 2.5" flange, which is slightly larger than the 2.25" flange used on the Gen 1 Turbo. This difference requires a specific adapter to ensure a proper seal.
FK8 PRL Install
The FK8 PRL Install is a crucial step in the downpipe installation process. It involves installing a high-performance downpipe on a Honda Civic Type R, specifically the FK8 model.
The PRL downpipe is designed to extract exhaust gases more efficiently, resulting in a noticeable increase in horsepower and torque. This is achieved through a free-flowing design and high-quality materials.
To install the PRL downpipe, you'll need to remove the factory downpipe and exhaust system, which can be a bit of a challenge. However, with the right tools and some patience, it's definitely doable.
Gutter Swan Neck
A gutter swan neck is a clever way to route your downpipe run from the fascia back under the soffit to the wall. It's achieved with two offset bends and a short piece of downpipe.
The essential components required to create a swan neck are two 112 degree offset downpipe bends and a short piece of downpipe, which should be sufficient to reach from the first offset bend back to the downpipe on the wall.
To measure the length of the downpipe, take a close look at the area and trim it to suit on site. This will ensure a neat fit.
Here are the key components you'll need to create a swan neck:
- 2 x Aluflow 112 Offset Downpipe Bends
- A short piece of downpipe (measured to reach from the first offset bend back to the downpipe on the wall)
It's worth noting that the length of the downpipe should be trimmed to fit snugly, allowing for about 35mm off the wall.
4.0T
The 4.0T engine is a beast, and we're excited to dive into its install on our FK8 PRL.
The 4.0T engine is a 2.9-liter twin-turbo V6 that produces 444 horsepower and 406 lb-ft of torque.
We'll need to make sure our engine is ready for the install, which means checking the engine oil level and ensuring it's at the recommended level.
The recommended oil level for the 4.0T engine is between the minimum and maximum marks on the oil dipstick.
A cold start is necessary for the install, so make sure to let the engine sit for at least 30 minutes before starting the process.
Gen 2 Turbo Heat Shield Replacement Kit
The Gen 2 Turbo Heat Shield Replacement Kit is a must-have for any FK8 owner. It includes two proper length aluminum spacers.
These spacers ensure a secure fit and prevent any damage to the surrounding area. Two proper length stainless steel M6 bolts are also included.
These bolts provide extra support and stability to the heat shield. Two stainless steel flat washers are also part of the kit.
These washers help to distribute the weight evenly and prevent any scratches or marks on the surrounding components.
Installation and Maintenance
To ensure a safe and successful downpipe installation, safety precautions should be taken first. This includes wearing protective gear such as gloves and safety glasses.
When connecting joints, it's essential to ensure they are clean and dry to prevent leaks. Apply Securbond gutter sealant to all connections to guarantee water tightness.
Downpipe clips should be spaced at approximately 1.5m apart and directly below any connections. This will help maintain the stability and integrity of the downpipe system.
To fit a downpipe, start by connecting a small piece of rainwater downpipe to the bottom of the running outlet, ensuring the length clears the bottom of your fascia. The downpipe should sit approximately 35mm off the wall.
Here's a quick rundown of the key components to install:
- 112 Degree Downpipe Bend
- Offset Downpipe bend
- Downpipe clips
- Downpipe connector
- Y Branch Connector
- Downpipe shoe
Remember to securely fix the first downpipe bracket to your wall with suitable stainless steel fixings, and use a downpipe connector to join two downpipes together end-to-end for a longer run.
Installation Steps
To get started with installing your downpipe, safety should be your top priority. Please take the necessary safety precautions before beginning.
The first step is to start with the Aluflow Running Outlet and Rock N Lock into place.
Make sure all joints are clean and dry when connecting the downpipe sections. This will ensure a watertight seal.
You'll need to apply Securbond gutter sealant to all connections to guarantee water tightness.
A small piece of rainwater downpipe should be connected to the bottom of the running outlet, ensuring the length clears the bottom of your fascia.
To create a swan neck, fit a 112 Degree Downpipe Bend.
Measure another small piece of downpipe to suit your soffit depth, allowing for the downpipe to sit approximately 35mm off the wall.
Cut this measurement with a chop saw or hack saw with a metal-suitable blade.
Another Offset Downpipe bend should be fitted to complete the swan neck.
Downpipe clips should be spaced at approximately 1.5m apart and directly below any connections.
Here's a quick guide to downpipe bracket spacing:
Downpipe brackets should be securely fixed to your wall with suitable stainless steel fixings, and each bracket should be tightly fitted around the downpipe.
To join two downpipe runs together, use a Y Branch Connector.
When joining two downpipes together end-to-end for a longer run, use a downpipe connector with a gutter bracket below.
Finally, finish with a downpipe shoe for a neat finish or run straight into a drain system.
Common Questions
Here's what you need to know about installation and maintenance.
You should check the manufacturer's instructions for specific installation requirements.

Importance of Shoes
A downpipe shoe is a crucial component in rainwater drainage systems. It's essential to have one in every application where the downpipe isn't running directly into a drain.
Running downpipes directly into the main drainage system can cause overcapacity and increase flooding risks. This is why it's vital to fit a downpipe shoe to direct rainwater away from building foundations.
In cases where downpipes do run directly into a drain, it must be a soakaway or surface water drain.
