Downpipe / Sports Cat

The mountune Sport Cat Down Pipe has been engineered 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.

A large catalyst cross section means increased exhaust flow compared to other smaller catalyst equipped down pipes on the market.

Constructed of 3” primary AISI 304 Stainless Steel mandrel bent tubing with a CNC machined flange that allows easy installation, whilst robust factory type mounting brackets and hangers are utilised to maintain perfect alignment and OE like fitment.

Also incorporated is a 6” stainless steel flexi section to help absorb shock, prevent OE hanger failure, and a reduced the chance of false knock signals causing engine power reduction.

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