VIDEO: Audi RS7 Sportback Sounds Better without OPF Exhaust Filter

In Europe, all new cars need to have an OPF particulate exhaust filter fitted to them. It’s been that way for some time now and these OPF filters have drawn the ire of European enthusiasts for muffling exhaust noise, especially on turbocharged engines. So when Euro-based enthusiast hear their favorite cars sans OPF filter, it’s usually an eye-opening experience, as evidenced by this Audi RS7 Sportback video from Auditography.


This new video features a Middle East-market Audi RS7 Sportback, which doesn’t havethe OPF filter equipped. So its exhaust is as loud and as full as it’s intended to be. And it sounds great.

The 4.0 liter twin-turbocharged V8 in modern performance Audis is a real gem. In RS7 Sportback-guise, it makes a whopping 591 horsepower and 590 lb-ft of torque. It has a deep burble at low rpms, not unlike an American muscle car. Unlike an American muscle car, though, its pitch changes as the revs climb, as it starts to growl and then wail. It’s a great sounding V8. Maybe not as aggressive as an AMG V8, nor as musical as a Lexus V8 but it’s pretty darned good.


However, the real takeaway is just how much better the RS7 sounds without the OPF filter. While that filter does help with emissions and is important for the environment, it certainly dampens the sound of modern performance cars and the Audi RS7 is no different.

Of course, if you live in Europe and want your RS7 to sound better, you can always fit an aftermarket exhaust, such as Akrapovic, Milltek or Supersprint, to name jus a few. That way, you ditch the OPF filter and gain a better sound than even the stock without the filter. You might not pass any emissions inspections different countries have but your car will sound good for sure.
