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.

This is the softest throw AND one of the biggest throw's we own! Just got two more! Can’t wait! These blankets are super strong, no shedding, no pilling AND the weight is perfect! I could literally go on! It’s most definitely worth the value! Go get one, you won’t regret it!

Gorgeous!
Color: Crown Script, Size: 50"x70"
I absolutely love this blanket! It’s of a perfect thickness - not so thick that you get really hot but it’s not too thin either so it’s definitely not cheap looking. It’s just right. The color pink is perfect, too. It’s that beautiful, pale, pale pink that’s so soft and attractive looking. And it’s super, super cuddly soft! Perfect for snuggling up with. I love the design, too. It has black crowns everywhere, all over the blanket, and gray polkadots in the background and then “Juicy Couture” written in black cursive all over it as well. I actually bought this for my granddaughter for Christmas because she loves Juicy Couture. I just know she is going to adore this blanket. So happy with my purchase! Definitely worth the price.

Soft, Warm, lightweight, Cozy
Color: Cream, Size: Full/Queen
When I first received this blanket I washed it by itself in cold water with detergent. I did not use a fabric softener or a fabric sheet. I air dried it completely and then put it in my dryer on air fluff for 10 minutes. No shedding and it came out just like I received it. I was concerned about shedding with some of the reviews but I had no issues with that whatsoever. It's warm yet lightweight. I didn't want anything that would make me overly hot because I'm always hot anyway. It takes that cool edge off when you still want your overhead fan on. My daughter said she likes it better than the one she has. I can't remember the brand. I feel it has a good quality. Just make note to wash it as instructed and it'll hold up well and look just as nice as the way you bought it. I'm not sure how the other reviewers that didn't leave 5 stars washed there's, but it couldn't have been the correct way.
