RS4 Exhaust

[galenthe2nd]

A friend has just bought a '07 RS4 and has heard that there is a map or modification that permanently adjusts the exhaust valve (other than setting the car to sport mode) thus increasing the power across the entire rev range. Is there any truth to this and if so what exactly is involved?

There are several companies out there who will upgrade the engine in the RS4, such as ABT, AMD, Revo, MTM and DMS Automative.
Milltek appears to be the favoured manufacturer for an aftermarket exhaust.
Capristo and Eiseman also do systems, as well as a bunch of other big names. However On a couple of the sites I've listed above, you'll see options for exhaust, too.

From the way you've written your post, it sounds like you're implying that the Sport mode increases power. Just to clarify that the Sport setting on the RS4 doesn't increase power, but opens up the valve on the exhaust and sharpens up the throttle response

Hope this helps!

It also gives you a cold ear because you end up driving everywhere with the window down.

There's certainly an element of truth here

Even more so if you have a milltek non-valve, non-res fitted
