Hi guys,

I have a Audi A4 TDI S Line on a 2009 plate. I would like the quad exhaust but don't much fancy replacing the rear bumper.

Is it possible to find a new plastic diffuser with the gap for a quad exhaust. Also if this is possible does anybody know if going from a double to a quad has any affect on the engine or performance?

I have seen a few quad rear diffusers but they all clearly state not for the S Line exterior.

Appreciate any help guys.

Gaz.

You should be able to get a S4 diffuser but not sure if this is a different bumper or not.

An aftermarket exhaust on a diesel without any other mods such as a remap won't do much for power.

I'm assuming you have the 3.0TDi? Miltek do a "quad style" replacement exhaust system for this. I know there are a few on you-tube, so worth having a look on there. I'm not sure about the diffuser though...but its definately doable.
