One of the VAG group companies Audi really became noticed as producers of performance road cars in the early 80’s with their release of the legendary Audi Ur Quattro, the world’s first all-wheel drive turbo production car. This was a real game changer which went on to win numerous world rally championships and sowed the seeds for their future high performance road cars. Scorpion has a heritage of producing high quality performance exhausts for these legends of the 80’s through to the highly sought-after performance models available currently.

Key Features:

  • Lifetime guarantee *
  • T304 motorsport grade stainless steel material
  • Cat/GPF-back (resonated or non-res, valved or non-valved) & high-flow turbo downpipes
  • Flexible upgrading, progressive tuning in stages
  • OE fitment, optional premium Ascari RS trims
  • Designed, developed, and manufactured in Derbyshire, UK since 1992

Our experienced technicians have developed an 80mm/3.15” Cat/GPF-back system, which can be optioned as either resonated (quieter) or non-resonated (louder). We're offering OE fitment finish that integrates with the in-built factory diffuser trims for a sleeker look.

Drivers will find that the system retains valve functionality, allowing full control of the car's soundtrack via the drive mode select button inside the car. This function enables on-demand noise.

Once installed, the new free flowing system improves the vehicles power and sharpens up throttle response as well as reduce the overall weight. One standout feature is the deep, throaty soundtrack, vastly improved over OEM.

Let others know you mean business with our premium carbon Ascari RS trims. Manufactured using high-strength carbon weave for a flawless look, silk finish steel inserts permit hot gasses to pass through without discolouring or weakening the carbon shell.

The Ascari RS trims are compatible with both OEM and aftermarket exhaust systems that fit the inbuilt OEM surrounds, offering a seamless swap. They are available for purchase packaged with our system, or as a standalone upgrade.

For those chasing more power, our selection of twin high-flow turbo downpipes are available. Constructed with a dimpled stainless steel outer thermal layer, they reduce heat soak and engine bay temps. Opt for the 200-cell sports catalyst for significantly improved flow over OEM; or choose the unrestricted de-cat offering peak gains (for motorsport use only).
