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.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eKey Features:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLifetime guarantee *\u003c\/li\u003e\n\u003cli\u003eT304 motorsport grade stainless steel material\u003c\/li\u003e\n\u003cli\u003eGPF-back system \u0026amp; GPF Delete available\u003c\/li\u003e\n\u003cli\u003eFlexible upgrading, progressive tuning in stages\u003c\/li\u003e\n\u003cli\u003eChoice of quad polished\/black ceramic Daytona or carbon Ascari tailpipes\u003c\/li\u003e\n\u003cli\u003eDesigned, developed, and manufactured in Derbyshire, UK since 1992\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eGPF-Back System:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eOur expert technicians have developed a 80mm\/3.15” GPF-back system with quad 100mm tailpipes, specifically for the BMW G90\/99 M5 model. Explore the full specification breakdown and available options below!\u003c\/p\u003e\n\u003cp\u003eThis exhaust comes resonated, fitted with a centre silencer that helps reduce drone and provides a more refined sound.\u003c\/p\u003e\n\u003cp\u003eDoes 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.\u003c\/p\u003e\n\u003cp\u003eOnce 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.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eTailpipe Styles:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eAscari: Our premium sport option, available exclusively in a matte carbon finish, highlights the distinctive sporty carbon weave.

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.
