Cat Back Exhaust V3 - RS

46

This part does not affect the base vehicle warranty.

The mountune V3 Exhaust for the Mk3 Focus RS is the result of countless hours of engineering and ongoing product development, offering a product that is simply unrivalled in terms of performance, sound and features.

Extensive effort was placed on producing a sound profile that replicated the personality of the RS with an aggressive note under full throttle, while maintaining a drone free experience during cruising and light throttle.

Produced from 304 series, 3” mandrel bent stainless steel tubing, the mountune V3 Exhaust also includes many features used in motorsport applications; each tube joint is connected by either V-Band or custom double slip-joint, ensuring the best seal possible while maintaining adjustability and lightness.

Full drive mode functionality is also maintained with the inclusion of an OE valve and motor assembly, requiring nothing to be switched over from the standard exhaust.

Large 4.5” laser-etched polished tips join the rest of the system via V-Band to allow even easier trim adjustment and future system customisation. 

Features:

  • 3" Stainless Steel tubing
  • 4.5" laser-etched polished trims
  • Includes new valve and motor assembly 
  • V-Band / double-slip joints throughout
  • High-flow rear silencer design
  • 10% lighter than OE system
  • Supplied with all required clamps / hardware
  • Compatible with OE downpipe / catalyst and mountune Downpipe / Sports Catalyst.

Total pops and bangs

This is a must for the rs !! The stock is very good but this literally blows the stock away !!!! Pops , bangs and burbles are what you get and no drone at at all on cruise ..... All Mountune parts are total quality as always , running 375 bhp at mo and just took delivery of Intercooler and pipes !! Roll on 400 !!

V3 cat back exhaust

When I took the exhaust out of the box I saw the pipe that joins to the back box was dented and was slightly oval. This was an absolute nightmare to get back into shape to fit together. Once fitted though this initial dissatisfaction was overcome by the improvement in the sound to the standard exhaust. This is what the car should have sounded like from the factory. It’s amazing. Thanks to mountune for the free top as a gesture as well.
