Frequently asked questions
Is this Downpipe suitable for both OPF and Non-OPF?
Yes. The set has the required connections and comes with cover nuts if you are not using them.
Do I need to adjust the software after fitting?
Recommended. With a decat or sports catalytic converter, an ECU tune may be required to prevent fault codes or abnormal readings and to maximise the performance benefits.
Does this fit the original catback exhaust?
Yes, the Downpipe is bolt-on and connects to the OEM exhaust without any additional modifications.
What is the difference between the decat and the 200-cell sports catalytic converter?
The decat offers the highest flow and the most pronounced sound; the 200-cell sports catalytic converter delivers high flow with additional filtering and often reduces the likelihood of emission-related warnings.
