MK7 GOLF R: How to get max power without removing your GPF/CAT [Milltek Exhaust, Racingline Remap]

Intro

Do you want to dramatically improve power, torque, intake and exhaust sound on your GPF equipped MK7.5 Golf R? 

The MK7 Golf R platform, including the 8V S3 and Leon Cupra 5F is a legendary car in the tuning world. With colossal performance gains available from simple bolt-ons and software upgrades, fantastic handling and great spec as standard. Some changes were made around 2017, which means some of these later cars have what is called a ‘Gasoline Particulate Filter’, or GPF, and sometimes referred to as a PPF, OPF too. This part helps to reduce particulate emissions, but mutes the exhaust system and limits the power and torque gains from Stage 1 tuning. You can remove the GPF, but your vehicle will no longer be road legal, which is a big issue if you would like to use your car on the road. 

There is a solution though, our Stage 1 package improves power, torque, releases hidden turbo sounds and the hidden exhaust note, whilst improving the engine bay and rear-end aesthetic, all whilst keeping your car road legal! 

RacingLine 5 Piece Intake Package 

The factory intake is incredibly restrictive on the MK7 Golf R. Not only does it restrict power, but it also hides a lot of the glorious intake and turbo sounds you want to hear from a performance car. To release the power, torque and sound, we install; 

RacingLine R600 Intake, this kit replaces the whole factory airbox and duct assembly, the much larger intake airbox, smoother intake path and air duct that uses the whole of the front grill. All of these elements allow for improved power, torque and sound on the stock car, and even larger gains when combined with the ECU software.

 

RacingLine Turbo Inlet Hose, this hose replaces the factory corrugated plastic hose. The factory hose being corrugated disturbs the airflow, slowing it down, and isn’t aesthetically pleasing. The RacingLine R600 Turbo Inlet Hose is internally smooth, eliminating restriction and is more aesthetically pleasing, and is available in Black, Red, Blue and Grey to furthe customise your engine bay. 

 

RacingLine Turbo 90 Inlet replaces the hugely restrictive, plastic turbo inlet. The factory turbo inlet tapers down to an outlet which is smaller than the turbo inlet, reducing performance. The RacingLine Turbo 90 Inlet has an outlet that matches the factory turbo inlet, maximising performance.

RacingLine Turbo Muffler Delete eliminates the last restriction on the intake. This part fits on the turbo outlet, it replaces the factory turbo muffler, which works as a silencer for the turbo and stifles flow. The RacingLine Turbo Muffler Delete replaces this part with an unsilenced part with minimal restritcion.

RacingLine Coolant Underhoses replaces the factory coolant hose that usually hangs across the factory airbox. This hose ruins the engine bay aesthetic, and the RacingLine Coolant Underhoses replaces this hose, routing it under the intake, out of sight.

Exhaust

The Milltek exhaust system fitted to this MK7 Golf R is the GPF back, this replaces the exhaust quite literally from the GPF back. This means it leaves the GPF and catalyst in place, remaining road compliant. The Milltek system has a larger internal bore, with freeer flowing back box and a choice of tips that fill out the rear diffuser, improving the rear-end aesthetic as well as sound. 

 

Range of Milltek tips that you can use:

1. Milltek Carbon Fiber Tips

2. Milltek Polished Tips

3. Milltek Titanium Tips

ECU & TCU software

To bring all of these upgrades together, the RacingLine OEM+ ECU & TCU tune is installed. The ECU optimises fuelling, ignition, boost and many other maps inside the ECU to dramatically improve performance. The TCU software optimises the gearbox for use with this improved engine output, optimising torque limits, shift points, clamping pressure and many other maps for improved gearbox performance with the ECU software. 

Peak output was lifted on this car from 318bhp & 438Nm to 379bhp & 541Nm, an improvement of 61bhp and 103Nm at peak.
