SLE Audi A4, A5 & Q5 B8 (2.0T FSI) 2009–2011 Catless Turbo Downpipe

The SLE Catless Turbo Downpipe is a performance upgrade for B8 Audi A4, A5, and Q5 models equipped with the 2.0T FSI engine. By eliminating the factory catalytic converter, this downpipe significantly improves exhaust flow, reduces turbo lag, and delivers a more aggressive exhaust note.

Constructed from T304 stainless steel, and TIG-welded with back-purging, it’s built for long-term durability under high-heat, high-boost conditions. This is a direct bolt-on solution, making it a hassle-free upgrade for enthusiasts seeking more power and sharper response.
