Product information
3,5" 90mm valved catback exhaust system - AUDI RS Q3 DNWA OPF - ECE homologated
Product description:

The 3,5" 90mm catback exhaust system is designed to handle power levels around 900HP and also offer a great sound, without having negative drone effects in the car. The system comes with a twin 2,75" 70mm pipe diameter, that goes into single 3,5" 90mm. At the smallest section the system offers a 3,5" 90mm diameter, which allows to handle 900HP. It is a plug and play exchange to the stock system, using the stock electric valve. Therefore the system can be controlled by the stock AUDI MMI / Dashboad switches (dynamique / comfort / individual) / auto). The exhaust system can be configured with or without middle silencer. If you choose the "street" option you have the middle silencers, and the system is street legal. The version without middle silencer "race" version does sound more brutal, but has no more homologation.
