FITMENT GUIDE
To complete the installation of the ARM S55 Track Exhaust, you will need an ARM Midpipe. Other 3.5" midpipes may work, but will likely require modification as the position of the ARM Track Exhaust connects to the midpipe on other brands is likely different than the ARM Midpipe.

PROFILE
The ARM S55 Track Exhaust is the perfect fit if you're looking for an aggressive sounding, lightweight, flame-throwing exhaust setup for your F8X! Designed specifically for track use, this exhaust system produces an aggressive exhaust note that will turn heads on and off the track.

The purpose of the ARM S55 Track Exhaust can be summed up in one word, FUNCTION. The goal of the ARM S55 Track exhaust is to get the exhaust gasses to the rear bumper in as smooth of an exhaust path as possible, while increasing exhaust gas velocity by utilizing a full 3.5" system from the downpipes back, all while minimizing overall weight. By replacing the OEM exhaust system with the ARM S55 Track Exhaust you will save over 40lbs!

When building your ARM S55 Track Exhaust you have the option of 2 different tip styles. One choice is the dual tip style, the dual-tip option will fill one side any standard diffuser including the OEM diffuser completely. It utilizes two of our S55 Exhaust Tips which mount onto the CAD engineered Y-Pipe.

The other, more aggressive option is the single exit style, which extends the 3.5" piping of the track exhaust outward a few inches past the bumper.

CONSTRUCTION
Built from high-quality T304 stainless steel and featuring mandrel-bent tubing, the ARM S55 Track Exhaust delivers unrestricted flow and reduced weight for your F80. The ARM S55 Track Exhaust continues where the ARM S55 Midpipe leaves off. The first section of the exhaust is the midpipe extension which extends the midpipe back towards the rear differential. This section of the exhaust includes a mounting bar which fits perfectly to the OEM exhaust hanger in that location.

The next section of the ARM S55 Track Exhaust is the axel-back section which connects from the midpipe extension to the rear tip(s). This section of the exhaust features a mounting bracket designed to connect into the original mounting point for the OEM muffler. This ensures the ARM system is secure and does not bounce or jostle during aggressive driving.

The ARM S55 Track Exhaust features a direct bolt-on design, there is no cutting or trimming of the OEM exhaust system. The ARM S55 Track Exhaust can be installed in approximately 45 minutes using basic tools.
