Aston Martin DBX Spool Race Downpipes

Spool race downpipes for the Aston Martin DBX bolt on to the M177.2 4.0L twin-turbo V8 to improve exhaust flow and turbo response.

Why you need it

The factory downpipes restrict flow right behind the turbos. These 304 stainless downpipes cut backpressure for faster spool, sharper throttle response and a more aggressive exhaust note, and with proper tuning they support more horsepower and torque.

Fits

• Aston Martin DBX 4.0 V8 (M177.2 twin-turbo)

Features

• Direct bolt-on installation
• 304 stainless steel, precision welded
• Catless or 200-cell high-flow catalytic converter option
• Reduced backpressure for faster spool and response
• More aggressive exhaust sound

Good to know

Choose catless for maximum flow and sound, or the 200-cell high-flow catted version to keep catalytic converters in the system. Power gains depend on a supporting tune. Intended for off-road and competition use only. Not legal for use on public roads in many areas.
