Details:

The catback system is a complete stainless steel, mandrel bent, cat-back exhaust. APR has seen gains of 16Lb ft of torque at the wheels on the dyno. The APR B7 S4 exhaust is a dual 2.25" system that begins at the factory Audi B7 S4 downpipes and continues to an innovative center muffler. The APR exhaust then splits and each mandrel bent pipes goes to its own muffler with twin staggered bevel-cut, round tips.

The APR CB100031 exhaust is very quiet and simply changes the tone of the B7 S4 V8s exhaust to a deep, unobtrusive sound. With TIG welding, fully stainless construction, and CNC'ed hangers, you will not find a higher quality system on the market.

Below is a video we made comparing APR's cat-back with the STaSIS cat-back... Just to give you an idea of a sound comparison.
