Manufactured from high-grade lightweight titanium, the Evolution Line exhaust system features one central and two side mufflers and a titanium collector, fed by larger-diameter stainless steel link pipes and custom-made flex tubes, fully insulated where they attach to the downpipes.
- A valve on each side muffler controls gas flow and aids the sound; each valve housing and the active X-connection (with its own valve) are cast in the in-house foundry
- Unique carbon fibre/titanium tailpipes, one each side, with a handmade carbon-fibre outer sleeve aligned to a sandblasted and coated titanium inner
- Acoustically tuned soundtrack from low rumble through mid-range to a high-frequency top end, with sharp rumble on downshifts
- Everyday comfort with no unwanted drone or excessive noise
- Power gain of 15.7 hp (m) at 6150 rpm and torque increase of 17.9 Nm at 6150 rpm, tested on the Akrapovič dyno against an Audi RS 6 Avant (C8) with the stock Audi Sport exhaust, with a weight saving of over 20% vs stock
- Optional Downpipe / Link pipe set (SS), Akrapovič Sound Kit and matte or glossy carbon fibre diffuser available
The Link pipe set (SS) L-AU/SS/6 is a mandatory product to the Evolution Line (Titanium) S-AU/T/2H (split into two codes for packaging reasons). Developed for cars without gasoline particulate filters and compatible with the original Audi trailer hitch.
