Deep Tone Industries x Toroing BMW G80/G81 M3 & G82/G83 M4 Equal Length Z Pipe Midpipe (2021+)

Transform the sound of your BMW S58-powered M car with the Deep Tone Industries x Toroing Equal Length Z Pipe Midpipe. Developed through a collaboration between Deep Tone Industries and Toroing, this innovative exhaust upgrade has quickly become one of the most sought-after modifications for the G8X platform, delivering a deeper, smoother and more exotic exhaust note without fundamentally changing the factory rear silencer.

Unlike conventional midpipes, this system features a 3D printed stainless steel Z-pipe crossover design, combining advanced manufacturing techniques with an equal-length exhaust layout to improve exhaust pulse timing. The result is a dramatic change in the character of the S58 engine, reducing the rasp and harshness many owners associate with the factory exhaust while enhancing turbo whistle and producing a richer, more refined soundtrack.

Manufactured using 3D printed stainless steel, this midpipe offers exceptional manufacturing accuracy, superior internal flow characteristics and outstanding fitment compared to traditional fabricated systems. Supplied with a Fitment Guarantee and 1-Year Warranty for the original owner, it represents one of the highest-quality Z Pipe options currently available for the BMW G8X platform.

What Is A Z Pipe?

The Z Pipe is the latest evolution in BMW S58 exhaust design.

Rather than merging both exhaust banks into a single pipe like a traditional single midpipe, the Z Pipe retains the twin-pipe layout but crosses the two pipes over in a carefully engineered Z-shaped configuration while maintaining an equal-length flow path.

This allows exhaust pulses from each turbocharger to arrive at the rear exhaust in a much more balanced and consistent manner, fundamentally changing the character of the engine without relying purely on increased volume.

Think of it as the next generation of equal-length midpipe technology.

Why Does It Sound So Different?

The S58 engine has earned an outstanding reputation for its performance, but many enthusiasts feel the factory exhaust note lacks the excitement of previous BMW M engines.

Owners often describe the standard exhaust as:

• Raspier than expected
• Metallic at higher RPM
• Harsh under load
• Lacking the depth of earlier M cars

The Deep Tone Industries x Toroing Z Pipe focuses on changing the quality of the sound rather than simply making the vehicle louder.

Owners typically report:

• Deeper idle
• Noticeably reduced rasp
• Smoother exhaust tone
• More exotic sound at higher RPM
• Increased turbo whistle
• More refined overall character

Rather than sounding like a heavily modified exhaust, the Z Pipe gives the S58 a more mature, premium and motorsport-inspired voice.

Why Choose A Z Pipe Instead Of A Single Midpipe?

For several years, single midpipes have been the most popular exhaust upgrade for the BMW G8X platform.

While they remain an excellent option, the Z Pipe takes a different approach.

Many enthusiasts who previously chose single midpipes are now moving towards Z Pipes because they deliver a more refined sound while retaining the character enthusiasts are searching for.

Is It A Performance Upgrade?

The primary reason enthusiasts choose a Z Pipe is sound, not outright horsepower.

However, the improved exhaust routing can offer:

• Improved exhaust scavenging
• Reduced exhaust restriction
• Better exhaust flow
• Potential small power gains on tuned vehicles
• Improved turbocharger efficiency

Compared to ECU tuning or downpipes, performance improvements are relatively modest, making this a modification chosen primarily for its acoustic benefits.

Precision 3D Printed Construction

Unlike conventional fabricated exhausts, this system utilises 3D printed stainless steel technology.

Benefits include:

• Exceptional manufacturing precision
• Superior fitment accuracy
• Optimised internal exhaust flow
• Complex internal geometry impossible with traditional fabrication
• Outstanding durability
• Premium finish

This advanced manufacturing process ensures each Z Pipe meets extremely tight tolerances for both performance and installation.
