mountune High Flow Turbo Back Exhaust - Focus ST 2013-2018

Includes High Flow Sport Cat Down Pipe and Exhaust system

mountune has been engineering exhaust systems for years with the objective towards increased power and response coupled with an enhanced exhaust tone and appearance. Our Focus ST (C346 ST) High Flow Turbo Back Exhaust system is manufactured from 2.5” (3" Down Pipe) , 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. We have also incorporated slip fit connections at various strategic points to allow for easy installation and adjustment.


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. Constructed of 3” AISI 304 Stainless Steel mandrel bent tubing with a CNC machined V-Band flange that allows easy installation. Additionally, robust factory type mounting brackets and hangers are utilized to maintain perfect alignment and OE like fitment. We also incorporate an 8” stainless steel Flex Section to help absorb shock and prevent OE hanger failure. Revised engine calibration may be required for optimal performance.

Turbo back May 9, 2017
Reviewer: Brandon from Morning View, KY United States  
I did a whole bunch of research on what kits give what sounds. I was going for something healthy but not obnoxious. This kit hit that ON THE HEAD. No drone what so ever. On top of sound, the performance I received after putting this on was astonishing. Added GOBS of torque and almost immediate turbo response. Well done Mountune. ST owners NEED this!

Love it March 9, 2017
Reviewer: Bruce Moberg from Auburn, WA United States  
Replaced 3" Cobb Catback system with 2.5" Mountune   turbo back system. Exhaust is very quiet and well mannered during normal commute type driving. Exhaust starts to sing when you mash the throttle and sounds great . I have experienced no drone or added NVH with this product. Install is a little tight toward back of car but fitment is great. I am very pleased with this upgrade to my car.

Fast shipping December 20, 2016
Reviewer: Keith Peterson from Kansas City, MO United States  
It will be a while until I have a chance to install the exhaust, but their service & communication is top tier.  They do an excellent job getting back to you on questions.

Quiet, but sounds great December 12, 2016
Reviewer: James Puckett from AL United States  
I bought my ST used with 3 in pipe from the turbo back and it was just too obnoxious. This exhaust sounds great and I can hear myself think. Obviously, its quieter that most aftermarket (3in) exhaust, but that is exactly what I wanted. High quality and easy to install. Good luck with that rusty V-band clamp on your old downpipe.
