The SLE Catless Downpipe is built to improve exhaust flow and performance for the B9 Audi A4 and A5 equipped with the 2.0T TFSI engine. By removing the factory catalytic converter, this upgrade reduces backpressure, improves turbo response, and delivers a more aggressive exhaust tone — perfect for street or track use.
Crafted from T304 stainless steel, and TIG-welded with back-purged construction, it’s made to withstand the demands of high-boost applications. It installs as a direct bolt-on with no modifications required.
