Description

The mountune Downpipe / Sports Cat has been engineered for the mk3 Focus ST 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. Constructed of 3” AISI 304 stainless steel mandrel-bent tubing with a CNC machined V-band flange that allows easy installation.

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.

Please Note: Revised engine calibration will be required for optimal performance and may emit the EML without it.
