SLE Downpipe – Audi RS4 & RS5 B9 (2.9T) 2018+

The SLE Performance Downpipe is designed to improve exhaust flow, reduce backpressure, and enhance overall performance for the 2.9L Twin-Turbo V6 engine found in the Audi RS4 and RS5 B9 models. By replacing the restrictive factory downpipe, this upgrade allows for better turbo efficiency, faster spool, and a deeper, more aggressive exhaust note.

Constructed from high-quality T304 stainless steel, this downpipe features TIG-welded and back-purged construction for maximum durability and performance under high-boost conditions. Expect increased horsepower, improved throttle response, and a sportier exhaust tone.
