Black Mamba Downpipe for A4 B8 / A5 8T 2.0T

The Black Mamba 2.5” (63 mm) Decat Downpipe was developed for 2.0 TFSI engines.

This direct bolt-on upgrade replaces the restrictive OEM catalytic converter and provides free flow between the turbo and the front pipe.

Better flow. Better efficiency.

Thanks to:

• 2.5” (63 mm) mandrel-bent pipe construction

• Precise TIG welds

• 100% T304 stainless steel

lower back pressure, faster spool, and improved turbo efficiency are achieved – especially with Stage 1 / Stage 2 tunes.

Key features

• Direct bolt-on installation
