    MBRP S4601304 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.

    PRO SERIES – T304 Stainless Steel is the absolute best material grade performance exhaust system that money can buy. It is designed and built for the most serious enthusiast who will settle for nothing less than best quality material and finish. Constructed from T304 mill finish stainless steel from end to end including the tip, it delivers optimal durability that keeps on looking its best for years. This easy to clean and maintain material is the product of choice for owners of muscle cars, euro, sport compact show vehicles or those who operate in severe weather environments such as extreme cold weather conditions.

    Great exhaust

    Exhaust sounds great in my 2017 Audi A3. No drone while cruising and loud when you want it to be. Just what I was looking for. The only complaint I have is that the clamps that came with the exhaust didn’t tighten down good enough so I had to go and buy different ones. Other than that I’m satisfied.

    Great sounding exhaust

    Exhaust sounds really good. Some drone at lower rpm’s but nothing too bad. Paired with a downpipe this exhaust sounds very aggressive

    Great sound

    The exhaust was very straight forward to install and sounds great after. The install instructions left quite a lot to be desired, sizes of socket and suggested wrench size etc. would have been nice. I used a 13mm for the stock butt joint and 15mm for the MBRP clamps, I also ended up using a torque wrench to tighten everything down as initially all the clamps were loose even when using a 1/2 inch socket wrench. All in all I would still recommend this due to the price/quality/sound. In the future I think it would be helpful if MBRP updated their installation instructions to include suggested tools for installation.
