G90 Signature Catback Exhaust System

Stainless Steel Valved Full Exhaust System – BMW G90 M5 (S68 Twin-Turbo V8-Hybrid)

Transform the performance and sound of your 2025+ BMW G90 M5 with our premium T304 stainless steel valved full exhaust system. Purpose-built for the S68 4.4L twin-turbo V8, this system is engineered to enhance exhaust flow, reduce backpressure, and deliver a deep, aggressive tone—without compromising daily drivability.

Designed using advanced techniques for a precise OEM-fit, this exhaust system integrates seamlessly with all factory mounting points and adds exhaust valve control which is missing from the OEM exhaust system. Whether cruising or pushing the limits, this system provides an immersive and exhilarating exhaust experience.

Key Highlights:

T304 Stainless Steel Construction: Built entirely from corrosion-resistant, mandrel-bent T304 stainless steel, this system offers long-term durability, heat resistance, and a consistent finish. Welded with precision using TIG methods to ensure structural integrity and leak-free performance under high-load conditions.

Remote control Exhaust Valves: Adds an electronic valve system controlled by a remote to replace the missing exhaust valves BMW did not provide with the stock exhaust. Provides a quiet, subdued tone in comfort modes and an aggressive, open-valve growl in dynamic settings—no tuning or coding required.

High-Flow X-Pipe Midsection: Centralized X-pipe balances exhaust pulses between banks, improving scavenging and enhancing the natural V8 rhythm. Reduces unwanted drone and enhances top-end acoustics under throttle.

Performance-Oriented Flow Path: Oversized and optimized 3.5” (89mm) piping diameter ensures efficient flow, minimizes turbulence, and maximizes power delivery throughout the rev range. Estimated gains of +18–22 hp and +20–25 lb-ft torque (with optional EPA catted downpipes).

Optional High-Flow Catted Downpipes: Available as an upgrade, our 400-cell GESI catalytic converters maintain emissions compliance (region-dependent) while increasing turbo efficiency and reducing spool time. CNC-machined flanges and heat shielding ensure fitment and thermal control.

Sound Engineering: Precision-tuned for a refined cold start, deep idle rumble, and aggressive throttle response. The system delivers a clean, motorsport-inspired tone without unwanted cabin drone—ideal for both spirited driving and long highway trips.

Quad 112mm Exhaust Tips (Multiple Finishes): Choose from brushed stainless, matte black; or carbon fiber quad tips to match your M5’s styling. Dual-wall design resists heat discoloration and adds a premium finish to the rear profile.

Direct Bolt-On Installation: No cutting, welding, or modification required. Includes all clamps, gaskets, valve motor brackets, valve motors with remotes and hardware. Fully reversible for lease or resale.

Specifications:

  • Material: T304 Stainless Steel
  • Tubing Diameter: 3.5” (89mm) from downpipes to rear exhaust
  • Valves: Electronic remote control plug-and-play
  • Weight Reduction: ~10–12 lbs vs. OEM system
  • Tip Diameter: 112mm (quad outlet)
  • Fitment: BMW G90 M5 (2025+) / G99 M5 Touring

Why Choose This Exhaust System?

This full stainless system offers the perfect balance of durability, sound tuning, and performance gains—without sacrificing luxury or OEM integration. Ideal for enthusiasts looking for a visceral exhaust experience with the peace of mind of factory compatibility and high-quality materials.

Unlock the full potential of your G90 M5. Let it breathe, let it roar.

Still Usefil for a Samsung S24 Ultra User
Color: Black
The Charging Pad: The pad is super flat (nearly the same thickness as the pad) and looks nice next to it or a similar mouse and keyboard pad. It works perfectly for my Samsung S24 Ultra without a case on it, but having a 'magsafe' style case would improve the experience. You do have to take a second to get the alignment right. It uses USB-C instead of cheaping out with a micro, and the status light is helpful. I don't think I own anything that can charge in the headphone area, and in case you're wondering, neither spot will charge a Samsung smartwatch (as expected). I'd nearly recommend this just for the charging pad since it's so unobtrusive on the desk. Just remember you'll need to route that wire out of the top of it somewhere. The mouse pad: The size is probably perfect for a typical keyboard and mouse user. I always have a 3D mouse on the left, and an extra long Coursair keyboard, so I prefer having a gigantic mat for all of that. But there is one feature of this mouse pad that I like more than most. The material doesn't attract every spec of dirt and hair in the universe, and it's easy to wipe off. Because of this, I use the pad under my 3D mouse and keyboard, with a larger full-desk pad underneath (including the mouse area). The felt material on the back keeps this locked to my desk, and unlike a rubberized pad, isn't going to turn into glue after a few years. I did test my mouse on the pad, and it feels fairly good. It's not too smooth, and is a bit easier on your hand, but very serious gamers may take some time to adjust.

Smaller and more expensive than artisian deskmats
Color: Black
These are slightly smaller than the standard artisan deskmats and double the price.. It's also about half the thickness, so there's not as much padding. This isn't a huge deal. if the felt is on the bottom, it doesn't grip to the desk very well. The wireless charger is okay, but I found it bulky. Having a small dedicated 3 in 1 charging stand was more convenient for me. If you have a heaver mechanical keyboard, you won't be able to lift this thing to see underneath it. Overall, this is an okay deskmat and it'll serve it's purpose when I'm washing my regular deskmat, but not my favorite.

Well crafted and easy to assemble, decorative and useful piece.
Color: Bronze
This ring/jewelry holder is a little bigger than I expected it to be, and definitely is more suitable to a nightstand or dresser than on a bathroom vanity. That being said, the construction is very sturdy and it can easily hold a lot of jewelry. This is a great gift for a jewelry collector who already has a ton of jewelry and needs an innovative way to store and display it. There are a ton of branches on the tree, and each can easily fit 4-7 rings or necklaces.

Quick shipment, beautiful but slightly bent.
Color: Black
It's a beautiful piece, it was delivered sooner than expected which it is a plus the only thing I noticed after opening package, the top of the stand was slightly bent, I don't want to try to fix it because I'm afraid it may break. Overall it is very stable beautiful jewelry stand. Not too big and not too small. Perfect size.
