Milltek GPF/OPF Bypass for Audi R8 V10 5.2L Gen 2 (OPF/GPF Equipped Models Only) (2020 onwards) – Filter Delete, Motorsport Use
This is Milltek's GPF/OPF bypass pipe for the Audi R8 V10 5.2L Gen 2 (OPF/GPF Equipped Models Only). It replaces the section of pipe housing the factory petrol particulate filter with a straight-through pipe, clearing the last major restriction left in a modern turbocharged petrol exhaust once a de-cat and remap are already in place.
It's aimed at owners already running a de-cat and a supporting remap who want to clear the final restriction in the system, not a bolt-on for a car that needs to stay road legal.
Because it removes the particulate filter, it's intended for off-road and competition use. A car with the GPF/OPF removed will fail an MOT emissions test and isn't legal to use on UK roads.

Is it road legal?
No. Removing the particulate filter means the car will fail an MOT emissions test, so it is for off-road and competition use only.
Do I need a remap?
A suitable remap is strongly recommended, as the engine management needs to account for the change in flow and sensor readings. Speak to your tuner before fitting.
Can I use it with my standard exhaust?
Yes. Milltek lists it for use with the factory (OE) exhaust system.
How long does it take to fit?
Milltek quotes approx. 5 to 6 hours.
What is it made from?
T304L aircraft-grade stainless steel, which is anti-magnetic and resists discolouration better than lower grades.
Is there a warranty?
Yes. Milltek products are covered against defects in materials and workmanship. Contact us with your order number if you have a problem.
