Scorpion Exhausts GPF Delete - BMW G20 M340i

This product alters a factory emissions control device and does not meet current emission laws. For motorsport use only.

BMW really came to be recognised as producers of performance saloons after the formation of their famous M Division in the 1970’s and a real game changer for them was the launch of the E30 M3 in 1986 which went on to gain numerous championship victories in touring car racing. One of the first exhausts Scorpion developed was their own performance exhaust for the E30 M3 and at the same time Scorpion introduced the legendary DTM tailpipe to the UK market. Ever since Scorpion has been at the forefront of producing performance exhausts for BMW’s M cars and numerous others.

GPF-Back System:

Our expert technicians have developed a 70mm/2.75” GPF-back system with quad 90mm tailpipes, specifically for the BMW M340i G20 xDrive model. Explore the full specification breakdown and available options below!

Does our system retain valve functionality? Yes! Drivers can continue to control the car's soundtrack via the mode select button inside the car. This allows the ECU to modulate the sound levels emitted from your Scorpion exhaust.

Once installed, the acoustically tuned silencers — featuring specialised, unique internals (on systems equipped with mid-silencers or backboxes) — and precision CNC mandrel-bent pipework enable the exhaust system to expel engine gases more efficiently. This results in enhanced power delivery, sharper throttle response, and reduced curb weight, thanks to the full stainless-steel construction. Designed for durability, our system offers exceptional longevity, even in the harshest conditions.

Tailpipe Styles:

Daytona: This design needs no introduction, the classic Scorpion Daytona slash-cut style with a modern twist on a timeless look. The Daytona is a great-looking option for everything from hot hatchbacks to flagship autobahn saloons.

STW: Put on your leather driving gloves as we embrace motorsport heritage with the classic STW straight-cut trim. Tried and tested, the straight-cut look delivers raw, unfiltered aesthetics, harkening back to a golden era of motoring.

OE Fitment: This option indicates that our exhaust system has been designed with an OE-fitment finish, seamlessly integrating with the factory-installed diffuser trims to provide a stealthy and budget-friendly appearance.

Tailpipe Finishes:

Polished: Premium T304 stainless steel polished trims undergo a meticulous multi-step buffing process, resulting in a long-lasting, mirror-like finish that stays shining. (Available for Daytona / STW trims only.)

Black Ceramic: The matte black finish provides a stealthy, modern look. The tailpipes undergo a specialised coating process, ensuring a durable and flawless finish. (Available for Daytona trim only.)

GPF Delete:

What are the benefits of a GPF delete? This additional pipework removes the highly restrictive Gasoline Particulate Filter, which otherwise significantly muffles the exhaust tone, creates excessive back pressure, and limits tuning potential. Removing the GPF typically results in a louder, more aggressive exhaust note and significantly improved tunability. (For motorsport use only.)

Turbo Downpipes:

Ready to push the limits — what are the benefits? We offer high-flow turbo downpipes for drivers and enthusiasts seeking maximum tuning potential — whether fine-tuning on the dyno or pushing every horsepower at the track. Scorpion’s advanced downpipe technology is engineered for uncompromising performance and built to endure.

Our downpipes increase horsepower, dramatically improve gas flow for better turbo spool and reduced back pressure, and amplify the exhaust note for a more aggressive, race-inspired sound. (For motorsport use only.)

Sports Cat: Equipped with high-performance sports catalysts featuring a 200-cell honeycomb design. This precision lattice structure offers significantly improved exhaust gas flow compared to the dense, high cell-count OEM catalysts. Emissions-conscious drivers can tune their vehicles while maintaining some level of control. Keep in mind that catalysts are most effective at their optimal operating temperature — not when cold.

De-Cat: Removes the catalyst entirely, allowing for maximum exhaust flow with no backpressure concerns — ideal for extreme high-horsepower builds. The purpose-built, smooth-bore design ensures optimal gas flow without the restrictions of a catalytic converter.

Interchangeability:

Scorpion’s interchangeable program offers flexible upgrades, allowing your exhaust to evolve with your tuning stages. Whether you’re looking to change the exhaust trim for aesthetics or require increased tuning capability with high-flow pipework, our system adapts to your needs.

Always check each product's technical data for fitment details before purchasing, as compatibility may vary, and interchangeability is not always guaranteed.

The Scorpion Advantage:

Precision-engineered Scorpion exhausts incorporate our cutting-edge track-to-road technology, sharing proven motorsport tech with you. Crafted from premium T304 stainless steel, designed to endure the harshest of conditions. CNC Mandrel bent construction provides unmatched gas-flow, enhancing throttle response and boosting BHP. The manufacturing process also ensures weight-saving gains compared to OEM.
