"We installed a $2699 Milltek cat-back exhaust to hear more of the RS4's V8. Just as with the stock exhaust system, pushing the "S" button on the dash opens the bypass valves in the rear muffers for more sound. It's boomy just off idle, but the screaming wail in the upper ranges turns heads the way the RS4 should have from day one."<ul><li><a href="http://www.stratmosphere.com/milltek_rs4_exhaust.htm">Milltek Sport RS 4 Exhaust</a></li></ul>

I saw that - nice!

Probably not going to do the down pipes on this car. So is the non-resonated too loud? I want it louder than stock but don't want it to be too much. whatever they have sounds like it could be just right.

Suggestions?

My personal opinion is that the non-resonated version of the exhaust is too loud for this particular application....but that's just my opinion.

Pete @ Stratmosphere

they acutally caught wind of our video clip and wanted to get close to that (no downpipes on their car). I think they had a lot of fun. With the valves you can definitely enjoy the non-resonated. -Pete

Absolutely perfect sound. Get on it and you hear it. Cruise and the cockpit sound level is still quite comfortable. Roll down the windows, and the music is sweet.

basically....gotta hear it for yourself and make your own decision

Have not heard either in person (only youtube), but I do want louder than stock (in S mode), but without "drone" while cruising. With S mode OFF, is the drone bad without the resonators? I mean...will it keep my soon to be newborn and 3 year old awake in the back seat?

Pete @ Stratmosphere

if you are super-conservative resonated without valves should do. -Pete
