Audi B8 A4 A5 Allroad 2.0T 3 Inch Catless Test Pipe

This 3 inch test pipe is an easy bolt-on alternative to a full downpipe upgrade for the Audi B8 2.0T. It replaces the most restrictive section of the OEM exhaust, the catted section bolted directly to the turbo.

Why you need it

More airflow and less back pressure can deliver up to 24 whp and 30 wtq on tuned cars, most noticeable low in the rev range. Expect sharper throttle response, faster spool, quicker acceleration and a deeper, more aggressive exhaust note even with the rest of the system stock.

• Audi B8 A4 (FWD and Quattro)

Good to know

Catless design: without an ECU tune or O2 sensor fix, expect a check engine light. Intended for off-road and competition use only, not for registered road use.
