The ARM S55 Single Exit 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 Single Exit 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 Single Exit Exhaust you will save over 40lbs!

The ARM S55 Single Exit Exhaust comes standard with the single 3.5" tip.  This is the more aggressive looking style which extends the 3.5" piping of the exhaust outward a few inches past the bumper.  You also have the optional Dual Tip design, 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 our CAD engineered Y-Pipe.  The Dual Tip option is available in Brushed Aluminum and Stealth Black color preferences.  If you select the Dual Tip option you will also receive the Single Tip in your kit, so you can change the look whenever you like!

Built from high-quality T304 stainless steel and featuring mandrel-bent tubing, the ARM S55 Single Exit Exhaust delivers unrestricted flow and reduced weight for your F80.  The ARM S55 Single Exit 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 Single Exit Exhaust is the axle-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 Single Exit Exhaust features a direct bolt-on design, there is no cutting or trimming of the OEM exhaust system.  The ARM S55 Single Exit Exhaust can be installed in approximately 45 minutes using basic tools.

Great value: These are my go-to work from home shirt
Material Type: Recycled Polyester, Color: Blue, Size: X-Large
I’ve been pleasantly surprised by these shirts and wear them weekly for Zoom calls, since I’m still working from home these days. I figured at the price point it was worth trying them out, and now I’ve bought several in different colors. They aren’t super soft, but they are comfy and look nice. I’m 6’1” ~220 pounds, and the XL slim fit still has plenty of room. I imagine the regular cut is incredibly boxy and oversized. The difference between polyester vs recycled polyester is inconsequential. I typically buy expensive golf shirts, and these definitely aren’t as nice. They are a fraction of the cost though and a great “beater” work shirt / hang out shirt. It’s nice wearing something that looks and feels decent, but if something happens to it, you can toss and it and pick up another for the cost of a chipotle burrito.

Great price, not great quality
Material Type: Recycled Polyester, Color: Black, Size: Small
Simple, straight forward all black polo. I am a size medium woman (with some room since I don't like form-fitting) and bought a men's small. Fits perfectly for my frame. Long enough to tuck in for my part-time extra weekend job uniform. Also suitable for the golf course. A little thin, and if you hold it up to light you can sort of see through it. *Not* flowy, soft and smooth fabric like a rash guard/sun shirt - more structured than that. But it's cool and does the job for the price under $10.
