SLE Audi RS6, RS7, S8 A8 C8 (4.0T) 2018+ Catless Downpipe

SLE Audi RS6, RS7, S8 & A8 C8 (4.0T) 2018+ Catless Downpipe

The SLE Catless Downpipe is designed to dramatically improve exhaust flow and reduce backpressure for 4.0T twin-turbo V8 engines found in the C8 RS6, RS7, S8, and A8. By eliminating the restrictive factory catalytic converters, this downpipe increases turbo efficiency, enhances throttle response, and delivers a louder, more aggressive exhaust tone.

Constructed from T304 stainless steel, the downpipe features TIG-welded, back-purged construction to ensure durability under high heat and boost. It’s a direct bolt-on upgrade that fits flawlessly without the need for cutting or modification.
