AUDI RS3

8Y (2020 – Present)

In addition to the Speedbuster module, we offer and professionally fit high-quality aftermarket parts, including premium exhaust systems. Our exhaust systems not only improve your RS3 8V’s performance but also enhance its sound and your overall driving experience.

Whether you’re looking to boost power, improve responsiveness, or upgrade your exhaust, we have the expertise and products to ensure your RS3 8V operates at its peak.

JFA Stage 1 Tuning Module - 470BHP / 475PS

This tuning package for the 2020-on Audi RS3 uses the Speed Buster Tuning Module. The tuned results are 470BHP and 620Nm.

We achieve this through a fully recalibrated engine management system (Speed Buster Module) that significantly increases both power and torque. 

Extensive testing and revisions on the road and our Mustang 4WD dyno have enabled us to greatly enhance power and torque, not just at peak values but across the entire rev range, improving drivability and expanding the power band.

The tuning process takes about 2-3 hours. We also offer optional before and after power assessments for an additional fee.

Valvetronic Exhaust System

The Armytrix Audi RS3 8Y exhaust system is a high-performance, valvetronic cat-back system that seamlessly integrates with the RS3’s original equipment. It features a main pipe diameter that transitions from 2X2.5 inches to 3.15 inches, enhancing the vehicle’s exhaust flow for better performance. This system includes unique features such as a catalytic converter and an OPF (Otto Particulate Filter) related fault code clearing mechanism, which helps to reduce the likelihood of a check engine light, particularly valuable for a full system installation.

Not only delivers improved performance and versatility but is also designed to be significantly lighter than the stock exhaust system. This reduction in weight is achieved through the use of high-quality materials like titanium alloy and stainless steel, which offer durability without the bulk. The lighter weight contributes to better overall vehicle efficiency and handling, enhancing both the performance and driving experience. This attribute is especially beneficial for performance cars like the Audi RS3, where every reduction in weight can translate to faster acceleration and improved dynamics.

One of the standout features of the Armytrix exhaust is its valve control technology, which allows the driver to switch between different modes – Smart, Neighbor, and Beast – offering control over the exhaust sound levels based on the driving environment or personal preference. This is managed either via a remote control or an app, which connects to the vehicle’s OBDIl port, allowing for easy adjustment of the exhaust valves.

Additionally, the system is designed to fit both left-hand and right-hand drive configurations and includes high-quality stainless steel construction for durability and performance. The exhaust is more than just a functional upgrade; it offers a combination of aesthetic enhancements with options for different exhaust tip finishes, contributing to a more aggressive and customised look for the Audi RS3 8Y Sportback.

Please note that if you prefer to switch to a different brand of exhaust, we can accommodate this request, but it will affect the overall cost. The displayed exhaust is what we recommended.

Cold Air Intake System

Performance Gain

  • Stock Turbo: 15-20hp, 13-18ft-lb
  • Flow Bench Data: Stock Intake 530 CFM | Eventuri Intake 840 CFM

Building on our RS3 8V system, we now offer an updated fitment for the RS3 8Y. Our intake system is designed to support all power levels, from stock to over 1000whp. It maximizes airflow while maintaining the lowest intake temperatures. Every component ensures a smooth, free-flowing path to the turbo.

The intake tube features an internal diameter of 103mm (just over 4″) and a smooth curvature from the filter housing to the turbo inlet. The specially designed filter has an outer diameter of 210mm (8.3″) and a filtration surface area exceeding 130,000mm². The patented Venturi housing maximizes internal volume within the RS3 engine bay, providing laminar flow to the turbo tube.

The duct seals the filter opening to the front slam panel, benefiting from an additional opening behind the hood, equivalent to a 7″ diameter hole. This design allows the system to flow 840 CFM at 28″ H2O, keeping intake temperatures minimal.

 

The Eventuri Difference

Our RS3 8Y Eventuri system features patented carbon fiber housings that create an aerodynamically efficient airflow path from the filter to the turbo tubing. Unlike conventional cone filters with heat shields, our unique design employs the Venturi effect for optimal performance.

Please note that if you prefer to switch to a different brand of exhaust, we can accommodate this request, but it will affect the overall cost. The displayed exhaust is what we recommended.

FAQ's

Do you offer a 12 month warranty?

Coming soon…

What is motorsport use?

Motorsport-exclusive components are explicitly designed for track use. While they can be installed on any vehicle, it’s important to note that using such parts renders the vehicle unsuitable for road use and may result in MOT failure.

Will the lifespan of my engine be reduced?

No! Our remaps are designed specifically to improve the performance of your vehicle whilst remaining within the tolerances of your vehicles’ components.

Sadly, in attempt to achieve ‘big numbers’ some other companies over tune engines, placing excessive stress on the engine, transmission, cooling systems, etc, leading to reduced life span and reliability of the vehicle. We pride ourselves in producing reliable remaps which do not over stress your vehicle but still produce impressive results.

What is covered with the 30-day money back guarantee?

In any case where a customer is dissatisfied with any ecu remap software supplied, within thirty days of the supply date, the customer can request their money back. In order for any refund to be processed, the customer must present their vehicle to our workshop and allow our technicians to restore the vehicle to its original state. On successful completion JF Automotive will refund the cost of the remap to the customer.

No refund can be granted unless the vehicle is returned to the original state by JF Automotive. The 30-day money back guarantee only applies to stage 1 remaps and does not apply to other services like pops and bangs, parts or dyno sessions.
If another modification is purchased alongside a tuning file, which relies on a remap to operate, only the cost of the file is covered by this guarantee. We reserve the right to withdraw this 30 day money back guarantee.

Read full Terms and Conditions

Can the remap be reversed?

Absolutely. We offer this service free of charge if the vehicle is brought back to us. We’ll be very surprised if that’s what you want after taking one of our remap products, however in the case of lease cars some customers prefer to put the car back to standard before returning the car. You might want it back to standard if you are visiting a dealer for warranty or service work, again we will do this for free. Should you lose your tuning files due to dealer actions or parts failure we will be happy to re-install the map onto your car free of charge where possible.

What if a main dealer wipes the map with a software update?

No problem, simply bring the vehicle back in and we will take a fresh read of your ECU and write you a new map file free of charge. We offer this as part of our lifetime software support.

Do I need to notify my insurance company?

Whilst the remap is undetectable to dealer equipment, you should notify your insurance company of any modification to your vehicle. Many insurance companies do not penalise you for upgrades of this nature, particularly if you’re tuning for increased economy however a failure to disclose modifications may invalidate your policy. You may wish to enquire with your insurer if the modification will affect your policy prior to choosing one of our services.

Why we don't you offer ECU remapping for £200?!

We get asked, “Why do some tuners charge as little as £150?” There are a few factors as to why we do not offer remapping for £100-£200!

We supply custom written files for each vehicle that we remap that take in to account condition, milage and customer request of each vehicle. Our services are fully insured with a 30-day money back guarantee and lifetime support for the tuning software supplied. We constantly invest in the most up to date tuning and diagnostic equipment and software and we offer a quality service to all our customers.

Overall our custom supplied tuning software is of the highest standard that we know of, so if you want the best of the best, choose JF Automotive.
