I popped out to Mountune in my Ford Focus RS to install the axle-back exhaust system, and what a sound it makes! It was inevitable following the install of the FPM375 package, but now it is done.
Not intrusive in general driving but with truly hilarious backfire crackles on lift-off and revving, and most importantly without disturbing the warranty situation at all. From stock the mkIII Focus RS is already an awesome machine, but after completing the FPM375 upgrade and now the exhaust it’s something else.
A huge thanks to Mountune for everything, this is amazing!
