An aftermarket exhaust does more than change the appearance of a vehicle.

It changes how the car sounds, how it feels to drive, and how noticeable the modification is from one situation to another.

For enthusiasts who want a more aggressive exhaust note without committing to the same volume all the time, Valvetronic Designs takes a different approach: valve control.

Its lineup combines valved exhaust systems, universal mufflers, valve-control hardware, midpipes, and exhaust accessories across a wide range of performance vehicles. At XPH, the Valvetronic catalog covers applications from BMW M cars and Toyota Supra models to Audi, Porsche, Mercedes-AMG, and other high-performance platforms.

The Advantage of a Valved Exhaust

A conventional exhaust system has a relatively fixed sound character.

A valved system gives the driver another option.

With the exhaust valves open, the system can deliver a more aggressive and unrestricted exhaust character. With the valves closed, the exhaust can be made substantially more subdued for situations where a quieter setup is preferable.

That flexibility is the core idea behind Valvetronic Designs.

Rather than choosing between an entirely quiet exhaust and an exhaust that is always loud, a valved system gives the driver greater control over the car's sound.

Valvetronic Designs for BMW

BMW is one of the strongest areas of the Valvetronic lineup.

XPH currently carries Valvetronic systems for numerous BMW platforms, including the G80/G82/G83 M3/M4, G87 M2, F90 M5, F8x M3/M4, F87 M2 Competition, G30 530i/540i and M550i, G20/G22/G26 M340i/M440i, M240i G42, X3M/X4M F97/F98, X5M/X6M F95/F96, and other BMW applications.

For owners of modern BMW performance cars, this makes Valvetronic particularly useful when the objective is to add a stronger exhaust presence while retaining control over how the vehicle behaves in different driving environments.

G8X M3 and M4

The S58-powered G80, G82, and G83 M3/M4 have become some of the most heavily modified BMW platforms on the market.

Valvetronic offers a dedicated valved sport exhaust for these cars, along with its HFD midpipe designed specifically around the G8X platform.

This allows enthusiasts to approach the exhaust system as a complete combination rather than treating the rear exhaust and midpipe as unrelated upgrades.

For owners building an S58-powered car around sound, airflow, and a more motorsport-inspired character, the Valvetronic lineup provides several ways to configure the system.

G87 M2

The BMW G87 M2 is another major application in the Valvetronic catalog.

Its valved sport exhaust is available in multiple configurations, allowing owners to tailor the system to their preferred setup.

The advantage is especially noticeable on a car that is used for more than one purpose.

A vehicle that sees daily driving, highway trips, spirited back-road use, and occasional events does not necessarily need the same exhaust volume in every situation.

F-Chassis BMW Applications

Valvetronic is not limited to newer G-Series BMWs.

The catalog also includes systems for earlier F-chassis platforms, including the F80/F82/F83 M3/M4, F87 M2 Competition, F90 M5, F30/F22/F32/F36 applications, and X3M/X4M F97/F98.

The range makes it possible to upgrade both newer and older BMW platforms while maintaining the same basic principle of adjustable exhaust sound.

Toyota Supra A90 / A91

Valvetronic also offers a valved sport exhaust for the Toyota Supra A90/A91.

The Supra shares its BMW-derived powertrain architecture with several BMW applications, but its exhaust system and overall vehicle character remain distinct.

For Supra owners looking for a more pronounced exhaust note while maintaining valve functionality, the Valvetronic system provides a purpose-built solution rather than a generic universal modification.

Audi Performance Applications

The Valvetronic lineup extends well into the Audi performance market.

Current XPH applications include:

• Audi B8/B8.5 S4/S5
• Audi B9 S4/S5
• Audi RS5 B9
• Audi RS6/RS7 C7
• Audi RS6/RS7 C8
• Audi RSQ8
• Audi TT RS Mk3
• Audi R8

The catalog also includes an exhaust valve/flap controller for the Audi R8 and Lamborghini Gallardo/Huracan.

That combination gives Audi owners options ranging from complete valved exhaust systems to valve-control hardware.

Porsche Applications

Porsche is another significant part of the Valvetronic range.

XPH carries systems for several Porsche platforms, including:

• Porsche 718 GT4 RS / Spyder RS
• Porsche 981 Boxster/Cayman
• Porsche 991.1 Carrera / S / GTS
• Porsche 991.1 / 991.2 GT3
• Porsche 991.2 Carrera
• Porsche 992 Carrera / Turbo
• Porsche 992 GT3 / RS
• Porsche Macan

These systems are aimed at owners who want to alter the character of their Porsche without giving up the flexibility of a valve-controlled exhaust.

Mercedes-AMG Coverage

Valvetronic Designs also offers valved exhaust systems for Mercedes-AMG platforms.

XPH's catalog includes applications such as:

• Mercedes-AMG GLC 63 / GLC 63 S
• Mercedes-AMG W205 C63 / C63 S
• Mercedes-AMG W204 C63
• Mercedes-AMG W213 E63

These applications bring the same adjustable exhaust concept to high-output AMG vehicles.

Beyond Complete Exhaust Systems

A complete valved exhaust is not the only way to use Valvetronic products.

The brand also offers individual components that can be useful when building or modifying an existing exhaust system.

Universal Valved Muffler Kits

The Universal Valved Muffler Kit is designed for custom exhaust projects where a vehicle-specific bolt-on system is not the preferred solution.

This makes the product particularly relevant to fabricators and enthusiasts working on custom applications. Valvetronic describes its universal mufflers as a way to add valve control to a wide range of builds.

Exhaust Valve Controllers

Valvetronic also offers electronic valve-control hardware.

Its Electronic Exhaust Valve Control Kit is designed to control OEM or aftermarket exhaust valves and can be configured for different valve-motor requirements. XPH lists configurations including applications such as the BMW G80 M3 and BMW F30 320i.

This can be useful when the exhaust itself is already installed but the owner wants more direct control over the valves.

Exhaust Tips

Valvetronic exhaust tips provide another way to finish an exhaust installation.

XPH carries both individual exhaust tips and 4-inch outlet options, allowing enthusiasts to change the visual finish of an existing exhaust setup or complete a custom exhaust project.

Midpipes

For BMW applications, Valvetronic also offers dedicated midpipe solutions.

One example is the BMW E9x M3 V2 Midpipe, while the newer G80/G82/G83 M3/M4 HFD Midpipe targets the S58-powered G8X platform.

These products allow enthusiasts to approach exhaust modification in stages instead of replacing the entire system at once.

Why Valve Control Matters on a Street Car

A track-focused car can often prioritize maximum exhaust volume.

A street car has to deal with everything else.

Cold starts, residential areas, long highway drives, traffic, passengers, and daily commuting can all make an excessively loud exhaust less practical.

Valve control provides a way to balance those requirements.

The result is an exhaust setup that can be aggressive when the driver wants it and more restrained when the situation calls for it.

Building an Exhaust Around Your Goals

There is no single ideal Valvetronic configuration for every vehicle.

Some owners may want a complete valved sport exhaust.

Others may already have an aftermarket exhaust and only need valve-control hardware.

A custom build may be better suited to a universal valved muffler, while another vehicle may benefit from combining a Valvetronic midpipe with a compatible rear exhaust system.

The important part is choosing components around the intended use of the vehicle rather than simply choosing the loudest available option.

A Broad Performance Platform

One of the defining characteristics of the Valvetronic Designs lineup is its breadth.

The brand covers everything from BMW M cars and Toyota Supra applications to Audi RS models, Porsche GT cars, Mercedes-AMG vehicles, and other performance platforms. Its product range also extends beyond complete exhaust systems into mufflers, valve controllers, exhaust tips, and midpipes.

That makes Valvetronic relevant to both straightforward bolt-on upgrades and more involved custom exhaust projects.
