Rs4 exhaust

Hi guys has anyone fitted b7 rs4 rear silencer boxes to a 2.0tdi b7 avant

I'd just look at fitting new tailpipes to your existing back boxes.

You could fit RS4 boxes but would be a bit harder to do in my opinion.

I've fitted S4 boxes to mine. The problem you may have with the RS4 variant is they have vacuum operated valves on them - I assume they're normally closed without vacuum so you'll be limiting your gas flow unless you can find a way to force them to stay open.

S4 boxes have no such thing, so unobstructed gas flow - I removed the resonator too. Noticed a definite difference to the power delivery of the car, just feels more 'free'!
