MBRP S46013CF Instructions

The Audi S3 Cat Back performance exhaust system is one to be reckoned with.

  • 4” O.D. 304 Stainless or Carbon Fiber Tips
  • Improved throttle response with enhanced sound
  • 3” Mandrel-bent tubing
  • High flow dual mufflers; +21% increase in flow
  • Helmholtz Resonator technology

This MBRP® quad rear exit performance exhaust design on the Audi® S3 with its innovative design including 3" Mandrel-bent tubing allows for a +21% increased in flow. This aftermarket exhaust system is carefully engineered to stay true to the Audi® S3 sporty appeal with a unique low-profile design that is perfect even for lowered cars.

The exhaust system is equipped with straight-through sound absorption mufflers and a Helmholtz Resonator that keeps the Drone level minimal for perfect highway driving conditions. But when you kick the car into Sport mode - watch out! This exhaust system goes to a whole new level in sound... 

The MBRP® Audi S3 exhaust system uses larger piping compared to the factory exhaust system with 3" OD piping, which then splits to a quad 2.5" design with a 3" y-pipe. The system uses T304 stainless steel. MBRP® offers a limited lifetime warranty on the Audi® S3 performance exhausts and stands behind the quality of work with excellent craftsmanship and MIG welding by MBRP welders.

The Audi® S3 exhaust tips come in both T304 stainless steel and Carbon Fiber double wall with T304 inner wall. This is really the cherry on top for this cat-back Quad Split rear exit performance exhaust system and blends in with rear bumper. Audi® enthusiasts should consider this exhaust system based on quality and overall sound upgrade that matches the sporty design of the Audi® S3.
