Just installed this Roush Cat Back on my buddy’s 2018 Focus ST, and it sounds great! Coming in around $600 un-installed, this cat back offers a nice tone at a respectable volume. During our short test drive we made it up to 60mph in 6th gear and found no drone at that cruising speed. We did not get a chance to take it up closer to 70mph. Vehicle has a Cobb cold air intake with the RS air box, stock down pipe, no tune. The Roush system appears to have a single straight through muffler.
