Cat Back Exhaust V3 [Mk3 Focus RS]

This part does not affect the base vehicle warranty.

The mountune V3 Cat Back 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 cat back 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.


Large 4.5” laser-etched polished tailpipes 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 tailpipes
  • Includes new exhaust valve (motor assembly will need to be swapped from OE exhaust and is shown for illustration)
  • V-Band / double-slip joints throughout
  • High-flow rear silencer design
  • 10% lighter than OE system
  • Supplied with all required clamps and hardware
  • Compatible with OE downpipe / catalyst and mountune Downpipe / Sports Catalyst.

    Sounds good

    Great exhaust, the exhaust shop commented on the quality. Had a bit of trouble getting it aligned perfectly but took it back in and it looks good now. Sounds great, deeper and louder without any drone.

    Who needs a stereo with the Soundtrack

    This was fitted by FJRS, I wouldn’t go anywhere else. This is how the RS should have sounded when it came from the factory. Have this fitted with the M380 and exhaust map and the RS feels and sounds alive. I personally think Mountune have got the balance spot on. The stereo has been switched off since the exhaust was installed. First class service all round . Get it, you won’t be disappointed!

    Game Changer

    Had this fitted at the weekend, Awesome product that has quality written all over it. If you don't have this on your car you don't really have an RS !! Pops and Bangs are so much better when putting foot to the floor .. Car feels better through acceleration. An awesome soundtrack. You wont stop smiling .. Thanks Mountune
