PROFILE


The ARM S58 Catted Downpipes increase power and torque on your S58-powered BMW while unleashing exotic sounds from your tailpipes.  The ARM S58 Catted Downpipes are one of, if not the best all around hardware upgrades for the G8X platform.  The ARM S58 Catted 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 Catted Downpipes one of the greatest all-around investments for your G8X.   

ENHANCE THE SOUND OF YOUR S58

The ARM S58 Catted 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 Catted Downpipes are built with SS304 stainless steel and backed by the ARM Motorsports Lifetime Warranty.  The ARM S58 Catted 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 Catted 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.

LOVE this brand. Have many of their styles. This is basically an unstuffed toy.
Size: Large, Color: Dinos Frills (Gray)
I have about 10 -12 different styles of the GoDog brand toys. It is like Xmas when my Malinois dogs get a new GoDog toy. Have loved this brand for many years and have some toys which have lasted 5-6 years -- minor "surgeries" stitch they back together -- until I retired them. They have never just worn out. Just to be clear: THESE TOYS ARE NOT CHEW PROOF. NO STUFFED TOY IS CHEW PROOF. However, this brand of stuffed toy is more chew proof than other brands. But if you are looking for a chew proof stuffed toy be advised -- IT DOES NOT EXIST!! No fabric is chew proof. Even if they invented such a fabric I would not want to ruin my dog's teeth by letting them try to chew through it. Protecting one's dog's teeth should be the highest priority. If a dog can chew through a PLASTIC KENNEL and even METAL WIRE KENNELS (yes, it happens) then they can easily chew through a puffy, fluffy stuffed toy. The "Chew Guard Technology" language may be misleading to some customers who are disappointed in the brand. I defend the brand and have used it for many years. No, I don't get paid or get free toys. Since I have had many styles within this brand and even have the pink version of this style I thought I knew what I was getting. This is basically a toy without stuffing which some people prefer. For whatever reasons my dogs prefer toys that are stuffed. Really stuffed with a firm density that they can sink their teeth into. So this toy will be OK. I can tell it will not be one of their beloved toys like some of the brand's other styles such as the purple brontosaurus. My fault for not reading more closely and assuming the grey version would be exactly like the pink version which is fully stuffed. If they get bored with these two I keep some of the Chew Guard toys stock piled. BTW one can wash and dry these toys. Yes, eventually the squeakers suck up some water and die but one can replace the squeakers. Also on Amazon. So I am willing to replace the squeakers a few times in the life time of one of these toys to be able to wash and dry them occasionally. Usually takes a couple drying cycles to get the heavily stuffed toys dried completely. If you have an aggressive chewer you may wish to look into Goughnuts dog toys or other hard rubber toys that are designed for aggressive chewers. Even then, with a determined dog, the Goughnuts toys can be chewed through. I think they offer a replacement guarantee. The other brand which has some toys of hard rubber is West Paw. An excellent brand that also offers a one time replacement. Bully Sticks are another option for chewers. PLEASE, PLEASE, PLEASE stay away from the hard plastic chew toys like the Nyla Bones. Hard plastic toys will destroy your dog's teeth over time. I learned the hard way (no pun intended) and ruined one of my dog's teeth. Vet asked if I allowed my dog to chew ROCKS !!!!!! Every tooth was cracked or fractured. Not wishing to pull teeth I had to pay for some very expensive root canals and caps. Vet's advise: If you can't dent the toy or chew with your finger nail DO NOT offer to your dog. Good advise to follow. Even some of the Bully Sticks (Costco Brand) are so hard they can chip or fracture teeth. Best for you and your dog.

Well made, minor issue was quickly resolved
Size: Large, Color: Dinos Bruto (Purple)
I purchased the Dino Bruto Dog toy for my labradoodle who is quite fond of squeaky, squawky stuffed toys and oddly enough has shown a preference for purple. I opened the package with my hound standing by waiting for his gift. I detached the tags and attempted to squeak the toy. It seemed difficult to squeak or honk. I tossed the purple Dino Bruto to my dog who excitedly chomped to squeak. The toy squawked a couple times and then just quit. My poor hound was staring up at me with that "what's up with this" look on his face. I tracked down the website for the GoDog toys, not going through the Amazon return process. I called the good people at GoDog and stated simply that my dog's favorite part of the toy failed quite quickly and I was wondering about guarantees. I was told to go to the website and file a replacement request. The replacement request required that I include a photo which I did as directed. I received an reply email within a couple hours which stated that a new toy would be sent out shortly. I am happy to report that we received a replacement toy, not the purple Dino, but a colorful wood duck. The squawker device works well and is still performing like new more than a month later. It appears that the squeaker is not those little plastic squeakers but the bigger heavy plastic bag, bladder, with what I visualize as a duck call sort of sound device. I am guessing because I haven't seen the inside of the GoDog toys. I have seen the guts of other stuffed toys which use this type of noise device. While our dog seems to enjoy the sound of the plastic bag, bladder set-up squawkers, they seem to fail quickly and I tend to avoid them because of this. The toys using this type of squawker that I have seen, use what looks like a cheap lightweight plastic bag which is not securely attached to the "voice box". Since the GoDog replacement toy is holding up so well, I am guessing GoDog uses a heavier grade plastic bladder coupled with reinforced construction. The purple Dino Bruto toy still looks new even after multiple times of our hound grabbing the purple toy, shaking it at us with his invite to give chase or play keep away. Since the squawker failed so quickly with the new toy, I figure it was just a defective item which does not reflect the general quality of toys from GoDog. One evening our neighbor was visiting while his pitbull was playing in our yard with our dog. Our patio door was open so our dog ran into the house and grabbed his purple Dino Bruto toy. He is a bit of a show-off with new toys. Our dog then went racing back into the yard, shaking his GoDog toy at the pitbull. A quick game of tug-of-war ensued. Since this is a new toy, our neighbor leaped into the game and took the toy away from the dogs. In that short time of tugging between the dogs, the toy held together and did not even pull apart at any of the seams. There were no puncture marks either. This is a game our dog has initiated before with the neighbor pitbull. Normally, the stuffed toys are ripped apart almost immediately. I was surprised and impressed with the quality of the sewing which appears to employ some sort of reinforced construction or heavier material. I plan to make more purchases from GoDog toys. The toys are a little more expensive than some stuffed dogs toys but they hold up so well I figure they are worth a few more dollars. They are great toys that hold up well and the company provides quick responses to inquiries. I consider this a winning combination.

Lasted from Nov 13th, 2024-August 20th, 2025 lol very impressive. She played with it nearly daily and loved the big squeak. The squeak box was just ripped out so she probably won’t play with it anymore. Happy to order another!
