This part does not affect the base vehicle warranty.
mountune has many years of experience in engineering exhaust systems with the objective of increased power and response, coupled with an enhanced exhaust tone and appearance.
The mountune Performance mk3 Focus ST wagon/estate Cat Back Exhaust system is manufactured from 2.5” diameter, AISI 304 stainless steel (EN58E) mandrel-bent tubing with lazer cut flanges. All muffler assemblies are robotically TIG welded AISI 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.
Crucially, the mountune cat back exhaust is the only exhaust system that will not affect your base vehicle warranty and in addition, comes with a mountune limited lifetime warranty*.

Overall the product was good but one of the tail pipes wasn't finished off very well as inside the righthand pipe you can see the angle grind marks which is disappointing as this is the part that is visable.
Looks good, sounds good (little more that stock, with induktion kit installed). Installed it myself, without lift, Took a few hours, and a few adjustments where needed after driven a while. The only thing that i would like is a little instruction, torque spec on the bolts.
Perfect build quality and sound, not too loud, but has a nice sound when accelerating
