PROFILE


The ARM S58 Downpipes increase power and torque on your S58-powered BMW while unleashing exotic sounds from your tailpipes.  The ARM S58 downpipes are one of, if not the best all around hardware upgrades for the G8X platform.  The ARM S58 downpipes improve throttle-response throughout the RPM range while stepping up the exhaust note, all without the need to replace the entire catback system on your S58. 

By reducing backpressure on your S58's turbos, you are able to spool faster and hit target boost quicker.  The outcome is more power sooner, resulting in faster 0-60 and 1/4 miles times.  If you are planning to tune your S58, this will benefit your G8X even more, as the backpressure will increase on S58's running higher than OEM boost. Making the ARM S58 downpipes one of the greatest all-around investments for your G8X.   

ENHANCE THE SOUND OF YOUR S58

The ARM S58 Downpipes will increase the overall volume of your exhaust, make the exhaust burbles more audible (even on OEM programming), and make the turbo spool significantly more noticeable.  Check out the links below for some sound clips of our Resonated S58 Catless Downpipes.  



CONSTRUCTION

The ARM S58 Downpipes are built with SS304 stainless steel and backed by the ARM Motorsports Lifetime Warranty.  The ARM S58 Downpipes starts with a 3" diameter precision CNC machined turbo v-band flange


Each downpipe utilizes either a Catless Resonator, or a 200-Cell High-Flow Catalyst.  The standard version is the Catless Resonated option.  If you select the Catless Resonated S58 Downpipes, your downpipes will have our resonators installed to help tune the tone of your S58 for a strong and aggressive sound while maximizing exhaust flow.  The resonators are completely hollow on the inside, there is no obstruction whatsoever. 



If you select the catted S58 Downpipes, the catalysts will replace the resonators found in the the catless/resonated downpipes.  The catted version sounds very similar to the catless variant, but will help with some of the exhaust odor.  The catted S58 downpipes will likely still produce a CEL.  To remove a CEL you will need a tune or a CEL Delete Kit. 



The longer downpipe (front downpipe) in the set utilizes a reinforced flex section.  The flex section is incorporated into the long downpipe to relieve stress on the turbo during aggressive driving.



Both ARM S58 Downpipes then transition to a 2.75" 2-Bolt connection to secure seamlessly to the OEM S58 midpipes, or any aftermarket midpipes that connects to the OEM downpipes.

Great Value for a Comfortable Home Office Chair
Color: Black, Size: Pack of 1, Color: Black, Size: Pack of 1
I’ve been using this chair for a couple of days now, and honestly, it’s been a solid upgrade from my old one. I work from home most days, so comfort matters a lot—and this chair delivers better than I expected for the price. The first thing I noticed was the lumbar support. It’s actually adjustable and makes a noticeable difference, especially if you tend to sit for long stretches. My lower back used to get sore after a few hours, but that hasn’t really been an issue since switching to this chair. The mesh back is also a nice touch—it keeps things breathable, which I didn’t think I’d care about until I had it. Assembly was pretty straightforward. Took me maybe 20–25 minutes without any frustration. Everything lined up well, and the instructions were clear enough. In terms of comfort, the seat is firm but not hard. It doesn’t feel like one of those super plush chairs, but I actually prefer that because it feels more supportive over time. The reclining feature is smooth, and I like that you can lean back a bit when you need a break. Overall, I’d say this is a great value for a home office setup. If you want something ergonomic and comfortable without spending a fortune, this chair is definitely worth considering.

Excellent Office Chair
Color: Black+white, Size: Pack of 1
I just received my TRALT Office Chair. First of all, I was impressed with the packaging of this item. When I opened the box each piece of the chair was wrapped in plastic or bubble wrap. Everything in the box arrived safely and without damage. Secondly, the instructions to assemble the chair were very each to follow. I was impressed with the Allen wrench which had a handle attached to it. This made screwing in the screws very easy. I was able to assemble the chair without any difficulty. Lastly, the look of the chair and the comfort is exceptional. I ordered the black/white chair which looks amazing. The comfort of the chair is really excellent. My back is supported by the lumbar seat and having the armrests being able to go up when not needed is wonderful. The quality of the chair is definitely worth the price.

a good choice
Color: Black, Size: Pack of 1, Color: Black, Size: Pack of 1
Assembled chair only to find that the lift cylinder was faulty. Would have preferred to be able to just get a replacement cylinder but calling China didn't seem like a viable option. Guessing which one & buying it online would involve paying for a good portion of what the chair cost. Customer service could only offer a replacement or refund. We're disassembling (so much fun?!) to send it back. The chair itself was very comfortable, assembled fairly easily and instructions pretty clear. Again, if we could only have asked the seller for the replacement part......**Update**...Or if the instructions that seemed so clear were clearer!, as we started to disassemble, we decided to see what would happen if the tension knob (see photo) was loosened. IT ALLOWED THE LIFT CYLINDER TO WORK. Not at all what the instructions say. At any rate, we're keeping the chair.

This chair is amazing
Color: Sky Blue, Size: Pack of 1, Color: Sky Blue, Size: Pack of 1
⭐⭐⭐⭐⭐ Absolutely love this chair! It was super easy to assemble—I had it set up in no time with clear instructions and minimal effort. The comfort level is fantastic; the seat cushion is just right and the back support makes it great for longer sitting sessions. The color is beautiful in person—clean, modern, and adds a fresh pop to the room without being overwhelming. I also really like the smooth wheels and sturdy build; it feels stable and well-made. Overall, this is a great combination of style, comfort, and value. Highly recommend!

Excellent Ergonomic Chair

I am incredibly impressed with this chair. The setup was a breeze and took me less than 20 minutes from start to finish. It is exceptionally comfortable, offering fantastic ergonomic support that keeps my back pain-free during long hours of sitting. The materials feel premium and highly durable. Plus, the included 5-year warranty is incredibly helpful and provides great peace of mind. I highly recommend it to anyone looking for a reliable workspace upgrade!
