mountune High Flow Exhaust - Focus ST 2013-2018


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 Exhaust system is manufactured from 2.5” , 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.

Mountune Exhaust '18 Focus ST September 15, 2018
Reviewer: Anonymous Person from Scottsdale, AZ United States  
Shipped lightning fast, had it in less than a week. Install took about 2 hours. Looks and sounds better than stock did. Seems to weigh less as well which is never bad.

Great quality, fit and finish August 10, 2018
Reviewer: Robert Johnston from Hanover, MN United States  
Great product, could be a smidge louder, a decibel or 2 would all that would be needed

Beautiful Exhaust December 2, 2017
Reviewer: JPGC  
Installed this cat-back about 500 miles ago. Very nice looking and well made exhaust. I used the Cobb hangers with it and the fit was on point. It is a subtle sounding exhaust, which is what I want. I do plan to add the mountune catted down pipe in the future so this should go well with it. If you want loud and raspy, this isn't the exhaust for you, however if you want a good sounding exhaust that doesn't drone or annoy your neighbors, this is the one.

Too quiet for me November 20, 2017
Reviewer: Anonymous Person from Kirkwood, MO United States  
I wanted to avoid the loud exhausts, but this one is barely different from stock.  Workmanship is indeed very good, although use of chrome plated bolts instead of stainless forced me to retap and rethread one of the bolt/nut combos for one clamp.  No instructions, I had to find them elsewhere, and they were needed - you must hammer in the heat shields to get the pipe going over axle into place (and then bend them back afterwards).  This is really too much money to be omitting this guidance.
