Audi RS4 - Milltek Exhausts - Resonate/Non-Resonate?

[B.J.W]

Hi.

Some advice appreciated here. I have my RS4 booked in for an exhaust upgrade next week. Going for the Milltek system (Cat Back, No valves) but can't decide whether to go for the resonated system or the (louder) non-resonated option.

It represents a fair cash outlay, so getting something I am going to be happy with long term is important. Concern about the resonated system is that it might not represent that much of a difference to the existing stock exhaust. However, whilst the non-resonated system sounds epic I have heard mixed opinions on whether it is the right choice to go for if the car is to used (as mine will be) on a daily basis (intrusive noise etc).

Are there any RS7 (B7) owners on here who can give me some first hand opinions on both options? Appreciate that individual interpretation will come into it, but a few pointers would be welcome.

Thanks in advance

The only system I get asked for these cars with regularity is the resonated, switchable system.

The non-switched resonated system is as you say, not enough different from standard to warrant the spend. The non-resonated, non-switchable system is too different. It is very boomy and droning at normal cruising speeds but without any means of making it shut up when you're not in the mood.

Just so I am clear, can you explain what you mean by switchable? Can't seem to find any info on the Milltek systems being switchable.

Milltek do RS4 systems both with and without the 'noisey mode' solenoids at the back. Switchable mimics the standard cars i.e. has a quiet setting and a loud setting. They also do cheaper systems that delete this.

The resonated, switchable system is the one to go for. With the valves closed there is a pleasant burble and a little bit more noise just to let you know it's there; in this setting it is never booming. Open the valves (on the sport button) and there's a lovely throbbing idle, more volume, fireworks on the over run....
