MAD BMW M3/M4 G8x S58 Axle Back Exhaust

Unleash the full potential of your G8x M3/M4 with the MAD Axle Back Exhaust system, designed to elevate both the sound and performance of BMW’s iconic S58 engine. Engineered with precision and passion, this exhaust system ensures your driving experience is as exhilarating as it is distinctive.

Key Features:

  • Enhanced Sound Quality: Say goodbye to the stock rasp and hello to a deeper, more resonant tone. The MAD Axle Back Exhaust is crafted to provide a rich, aggressive exhaust note that embodies the spirit of performance, enhancing the S58’s inherent roar without overwhelming cabin noise.

  • Increased Flow and Performance: With a larger tubing diameter of 76mm (compared to the stock 70mm), this system reduces backpressure and promotes smoother exhaust flow, resulting in noticeable gains in horsepower and torque. Expect a robust performance boost, with up to +5 HP and +5 lb-ft of torque, enhancing both acceleration and throttle response.

  • Versatile Exhaust Modes: Featuring a valved design, the MAD exhaust system allows you to switch between a subdued, deep tone during low-speed cruising and an aggressive, near-straight pipe sound at high loads. The stock exhaust valve actuators are retained, ensuring seamless operation via the M-drive settings, giving you control over your car’s sound profile.

  • Quality Construction: Built to last, the entire system is made from 100% T304 stainless steel, ensuring durability and resistance to corrosion. TIG-welded for superior strength and visual appeal, the exhaust system is meticulously brush-finished, offering a sleek, polished look right out of the box.

  • Seamless Integration: Designed for a factory-like fit, the MAD Axle Back Exhaust includes all necessary mounting hardware for easy installation. The quad 4-inch (100mm) clamp-on tips are engineered to fit perfectly within the factory cut-outs, enhancing the car’s aesthetics with a refined, OEM+ appearance.

  • Optimized for Performance: The system’s drone-abatement technologies effectively reduce cabin resonance, providing a pleasurable driving experience without intrusive noise. Whether you’re cruising on the highway or tackling twisty backroads, the MAD exhaust ensures a harmonious blend of performance and comfort.

Specifications:

  • Diameter: 76mm tubing for increased flow

  • Tips: Quad 4-inch (100mm) clamp-on tips

  • Weight: 7 pounds lighter than the stock axle-back (Stock: 44 pounds vs. MAD: 37 pounds)

  • Construction: 100% T304 stainless steel

  • Compatibility: Connects to factory midpipe (cutting required) or MAD single midpipe (no cutting required)

  • Includes: Extended valve harness and all necessary mounting hardware

High Quality Comfort!
Color: 01 Sage Green, Size: Queen (90" X 90")
This is definitely one of the most comfortable blankets I have ever owned. The material is thick, soft, warm, durable, and resistant to shedding & fibers breaking off. All of these favorable qualities work together to create optimal sleep conditions, and I would say it protects against cold temperatures in the environment (natural air & A/C, for example) very well. It is SO extremely cozy!!! It has become a comfort item of sorts, as well. It fits my Queen-sized bed absolutely perfectly. I've been searching for a blanket to fit my entire bed, and this blanket most definitely is the one. When this blanket is nearby, it's nap time! I love the the slightly raised texture of this blanket's material, and the checkered pattern adds a subtle, yet stylish touch to its overall appearance.

Loving my Bedsure Blanket
Color: Cream, Size: King (108" X 90")
I love this blanket. It’s for summer use & is the perfect weight. I feel both cozy and cool! Plus color & size are as shown. I washed it immediately and it was easy & came out soft; no shrinkage or shedding in the dryer.

Very soft. Light Blue is more of a sky blue
Color: Light Blue, Size: Throw XL (50" X 70")
Very soft, pretty thin, and a little stretchy. Overall, it looks nice. I would say it's a little thin for the colder weather, but great for the warmer months. I got the light blue, and it is a little more sky blue than true baby blue. I wish it were a true blue, but it's close enough that I'll keep it rather than go through the return process. I washed it, and little fuzzies came free, but nothing too alarming for a first wash. Hopefully, it doesn't do that every time. With how thin it is, there'll be nothing left eventually.

Super soft and strong , really nice blanket
Color: Navy, Size: Queen (90" X 90"), Color: Navy, Size: Queen (90" X 90")
This blanket is so soft. This blanket has stretch to it which is nice for tucking under mattress. Easy to lay out and fits perfectly on a queen bed, perfect amount of hangover. Great quality blanket. I did wash before I put on the bed and it did great. Shed in dryer but that’s easy clean up in vent. No shedding on bed after washed. I laid on bed before washed and it only shed a small amount, not much. I absolutely love this material, strong yet super soft. Definitely a great blanket to buy! You’ll love it.
