The mountune Downpipe / Sports Cat has been engineered for the mk3 Focus RS to reduce exhaust back-pressure at the turbocharger, allowing faster response and additional power.
Features include a large diameter 5” motorsport-type, 200 cell count metal substrate honeycomb catalyst, to ensure effective, ultra high flow performance in extreme environments.
Additionally, robust OE-type mounting brackets and hangers are utilized to maintain perfect alignment and OE-like fitment. Also incorporated is an 8” stainless steel flex section to help absorb shock and prevent OE hanger failure.
Supplied with adaptor sleeve to suit either the OE cat-back or mountune cat-back exhaust.
Revised engine calibration will be required for optimal performance and may emit the EML without it.
Features:
Recommended to fit in conjunction with mk3 Focus RS Cat Back Exhaust.
Paired with the catback exhaust this produces the perfect volume and sound. With the valve closed it's quiet enough to leave the neighborhood and cruise with no drone, with the valve open the sound is perfect for those spirited drives. Very happy with the product and the shipping across the pond. The install, on the other hand, was tough but worth it.
Purchased at Ford fair this is a work of art to look at quality welds gives cars deeper sound and quicker turbo response a real improvement of stock just waiting for M400 parts to complete package
Was a bit unsure about this as the V3 exhaust is loud enough at 5/6am so didn’t want anything too loud as I’m sure the neighbours wouldn’t appreciate it. When this is combined with the V3 exhaust, on start up and normal driving, somehow barely sounds any louder than before. When you get the change to put your foot down and open it up though, you certainly know it’s there. The roar and sheer noise this thing helps the car to produce is insane!! Definitely something I’d recommend, after all, you don’t buy a RS to blend in do you?
