Fourtitude have fitted a Milltek Sport non-resonated cat-back with exhaust valves to their own Audi RS 4 B7 V8 and said:
Just wanted you to know that the car has been transformed after the exhaust fitting - it feels and sounds much more aggressive and for that sole reason, am extremely pleased...great product!
"On the highway, sport mode is absolutely amazing; words can't accurately replicate or describe the sound. We couldn't be more pleased with the performance, look, and sound of the Milltek valved cat-back exhaust system on our RS 4."You can read more in our 'Milltek in the Press' section or view the article, including dyno tests and photos, in full on the Fourtitude website.
