SLE Test Pipe – B7 Audi A4 (2.0T EA113)

The SLE Test Pipe is engineered to replace the restrictive factory catalytic converter on the B7 Audi A4 2.0T, unlocking maximum exhaust flow and performance. By removing the most restrictive component in the exhaust system, this test pipe allows your turbocharged engine to spool faster, produce more power, and deliver a sharper, more aggressive exhaust note.

Expect noticeable gains in horsepower and torque — up to +20whp and +25wtq on tuned vehicles — along with quicker throttle response and reduced turbo lag. The result is a more responsive, exciting driving experience, whether on the street or track.

Crafted from 3" T304 stainless steel, the SLE Test Pipe ensures durability and precise fitment. It features CNC-machined flanges for a leak-free seal, two O2 sensor bungs for factory sensors or block-off plugs, and a reinforced mounting bracket for secure, OEM-style installation.
