Scorpion Exhausts - Audi RS3 & S3

• Cat-back and cat/GPF-back systems: rear-section systems in 80mm pipework for RS3 (8V/8Y) and S3 (8P/8V/8Y).
• GPF-back systems: for later particulate-filter equipped RS3 8Y Sportback models.
• Downpipes: 100mm downpipes listed for RS3 8V/8Y, plus 76mm and 80mm options for S3 8P, 8V and 8Y (some shared with Volkswagen Golf R).
• Sports cat and catless turbo downpipes: listed for S3 8Y Sportback and Sedan.
• Secondary catless pipes and centre muffler delete pipes: for RS3 8P/8V and S3 8V/8Y.
• Trims and hardware: Ascari RS carbon fibre tailpipe trims, exhaust accessories and exhaust tunnel braces.

Audi uses chassis codes to separate generations, and they are the quickest way to confirm the right listing. The RS3 runs 8P (2011-2012), 8V (2015-2020) and 8Y (2021 on); the S3 runs 8P, 8V and 8Y. Body style matters as well, with Sportback and Sedan listings often differing.

Also check whether your car is fitted with a petrol particulate filter (GPF), as this determines whether a cat-back, cat/GPF-back or GPF-back system applies. Pipe diameters are stated in each product title, and some downpipes are shared listings with Volkswagen Golf R or Audi SQ2. If you are unsure, check your build date, VIN and current exhaust layout before ordering.

Fitting typically calls for a hoist or safe vehicle support, a full spanner and socket set, penetrating fluid, new gaskets or clamps where required, and space to manoeuvre long sections of pipework. Downpipe and sports cat changes may also involve oxygen sensor removal and, in some cases, an ECU calibration.

Installation by a professional workshop is recommended. Removing or replacing catalytic converters and particulate filters may affect the emissions compliance and road legality of your vehicle, so check the rules in your state or territory before proceeding.

Will an 8V system fit my 8Y RS3?
No. The 8V and 8Y are different generations with different exhaust layouts, so always order to your chassis code.

What is the difference between cat-back and GPF-back?
A cat-back system starts behind the catalytic converter, while a GPF-back system starts behind the petrol particulate filter fitted to later models.

Are Sportback and Sedan parts interchangeable?
Often not. Body style changes the rear section length and hanger positions, so follow the body style stated in the product title.
