Cat Back Exhaust [Mk3 Focus ST]

The new mountune  mk3 Focus ST EC-Approved cat back exhaust system and now Non Resonated option is manufactured from 3.0” diameter,  304 stainless steel (EN58E) mandrel-bent tubing with laser cut flanges. All muffler assemblies are robotically TIG welded 304 stainless steel for long life under extreme performance and feature consistent internal diameter throughout the entire length of the assembly.

To ensure improved performance while controlling sound, each muffler includes a three-layer hybrid synthetic sound absorption packing that eliminates droning, booming, and other undesirable tones. Tubing diameter also has a major impact on sound quality and careful consideration was given to size and performance.

Also incorporated are slip-fit connections at various strategic points to allow for easy installation and adjustment.
