SLE Test Pipe – B8 / B8.5 Audi A4 / A5 / Allroad / Q5 (1.8T / 2.0T EA888 Gen 1/2)

SLE Test Pipe – B8 / B8.5 Audi A4 / A5 / Allroad / Q5 (1.8T / 2.0T EA888 Gen 1/2)

The SLE Test Pipe is designed to replace the restrictive factory catalytic converter for maximum exhaust flow and power gains. By eliminating the most restrictive part of the exhaust system, this test pipe allows your 1.8T or 2.0T engine to spool faster, make more power, and deliver a more aggressive exhaust note.

Expect significant gains in horsepower and torque — up to +24whp and +30wtq on tuned vehicles — along with sharper throttle response and reduced turbo lag. The result is quicker acceleration and a more exciting driving experience.

Constructed from 3" T304 stainless steel, the SLE Test Pipe offers precise fitment and long-term durability. The design features CNC-machined flanges for a leak-free seal, two O2 sensor bungs, and a reinforced mounting bracket for secure OEM-style installation.
