Invidia's most popular exhaust system.

Specifically designed to fill the sound gap between the Q300 and N1 system, the R400 produces a unique, agressive note while minimising harsh cabin noise (particularly at highway speeds). The R400 muffler was designed using years of experience from Invidia's engineers to allow the perfect balance between unrestricted exhaust gas flow and sound dampening. This exhaust system will provides a pronounced exhaust note throughout the entire RPM band even when only installed as a cat-back system. The R400 muffler design also looks great with a race inspired design that will turn heads.

The Invidia R400 Exhaust takes quality, performance and looks to a new level.

From start to finish the Invidia Exhaust Systems are designed with performance in mind with the exhaust route carefully selected to ensure minimal bends, allowing for an unobstructed exit of exhaust gases with minimal restrictions and turbulence. This will allow for improvements in both horsepower and torque, along with improvements in throttle response with a reduction in turbo lag for turbocharged vehicles. Additionally, you get the reward of an aggressive exhaust note.

Cobb Tuning SF Air Intake System

Cobb Stage 1+ by Got it Rex w/Accessport, Intake, Invidia R400 Cat Back - Subaru STI VAB 15-21 (4)

This C.A.R.B. approved intake and integrated airbox looks great and has the combined benefits of a short ram intake and a cold air intake without any of the negatives. This system utilizes several unique features in an effort to maintain optimal flow for performance while minimizing turbulence that can cause engine management problems. From a custom conical cloth air-filter element, we use a CFD-designed velocity stack leading to an unique air flow straightener grid. This straightener grid is specifically designed to smooth the incoming air flow as it passes the Mass Air Flow sensor for precise readings. This eliminates the "dead spots" experienced by other aftermarket intakes due to turbulence.

No other aftermarket Subaru intake system utilizes these critical design elements. In order to provide a system that looks as good on the outside as the technical advancements happening on the inside, we utilize a one piece design constructed from a high temperature plastic composite. Not only does this save weight compared to the previous metal design, the plastic composite material offers much better heat rejection properties that help keep intake air temperatures cooler. In contrast, intake systems constructed using metal castings or piping can actually retain underhood heat and in turn heat the incoming air.

The SF Air Box adds the benefits of a cold air intake to the outstanding performance of the SF Intake. The factory inlet directs cold air from the front grill to the SF Air, which encloses the SF intake. Hot engine bay air that robs horsepower is prevented from entering the intake system. This unique design also separates rainwater from the intake air, eliminating the water ingestion issues that plague in-fender cold air intakes. Calibrations All aftermarket intakes for 08+ Subarus require tuning in order to ensure the MAF sensor reads properly and the engine operates within safe parameters. COBB Tuning has you covered with Off-The-Shelf Maps for the Accessport, making it as easy as install, flash and go!

Cobb Tuning Redline Carbon Fibre Air Intake System

The Redline Carbon Fiber Intake seamlessly blends performance and aesthetics to bring the ultimate intake for your 2015-2021 WRX STI. Constructed of 2x2 twill carbon fiber and finished in a high quality gloss clear coat, the intake system's presence in your engine bay does not go unnoticed.


The main airbox is constructed of multiple layers of 2x2 twill carbon fiber sheets for a true carbon intake through and through. High quality gloss clear finish provides fade resistance from heat and UV light. A bespoke black Redline badge sits at the front of the integrated intake ducting. Air is filtered through a 35% larger (when compared to the standard SF Intake) pre-oiled filter and routed to the MAF housing which is bolted to the airbox by way of a black anodized billet aluminum adapter. The wire-reinforced black silicone coupler is sealed on either end with black anodized clamps for a very sleek install. A second billet plate can be removed from the fender side of the airbox to increase airflow and audible intake sounds of the system.

Velocity Stack MAF Housing

This intake system utilizes several unique features in an effort to maintain optimal flow for performance while minimizing turbulence. A custom conical air-filter element, CFD-designed velocity stack and unique air flow straightener grid are designed to smooth the incoming air flow as it passes the Mass Air Flow sensor for precise readings. The one piece high temperature plastic composite design saves weight and reduces heat transfer.


Installation of the Redline Intake is as simple as it comes for intakes with an integrated airbox and scoop. Follow our detailed instructions to install the supplied brackets and the entire assembly can be dropped in within a few minutes. Serviceability of the intake air filter is also straight forward once the initial installation has been completed.

Got it RexOff the shelf (OTS) maps for Cobb Accessport

Our goal is to provide a safe tuning foundation for modifications on your vehicle utilising in-house developed performance parts that have been rigorously tested and professionally tuned. We will only provide E-tuning for proven and tested parts that we use in-house. This means the car requires a list of approved brands only.

Our off the shelf options are designed to be used in conjunction with our GIR CAI, or Process West CAI or Cobb CAI in either Stage 1 or Stage 2 configurations. Both Stage 1 and Stage 2 maps are provided, just choose CAI option on checkout.

  • Our Stage 1 map is designed for a stock vehicle with the only engine modification being a cold air intake with or without a cat-back exhaust
  • Our Stage 2 map is designed for a vehicle fitted with choice of cold air intake and either a high flow catted downpipe or a full turboback exhaust

We currently offer both Stage 1 and Stage 2 options for the following models:

  • 2015-2021 VAB WRX STI

Common Questions:

I have a Cobb Accessport already, how do I get the correct map for my car?

This can be checked using the Cobb Accessport hand piece in vehicle via the Identify Vehicle option. Alternatively, if you are purchasing the Accessport through us, a drop down box is provided before checkout to input your year and model of vehicle. We will confirm this with you before sending.

How long does the process take?

Allow a week on average depending on workload and quality of datalogs sent

Can I use the OTS maps with different mods to ones offered?

No. We have structured this service to be as focused as possible and this does limit scope. As such, the tunes are offered for the approved mods only. This greatly benefits repeatability and proven results.

What risks are involved?

As with any modifications or tuning on a vehicle, there are inherit risks involved. Pushing your car past the factory intended power levels can introduce increased wear and risk to engine reliability. The responsibility is on the owner to ensure the car is of sound mechanical operation before and after undertaking modification. Modifying or tuning your vehicle WILL void your factory warranty.

Datalogging involves driving the car under varied conditions to get the required data quality needed to tune vehicle. This includes under power. You are required to not exceed/infringe on your state and territory road rules.
