Bull-X Downpipes Audi RS6/RS7 C8/4K 4.0 TFSI quattro 600HP

These Bull-X downpipes can be exchanged 1:1 against the oem downpipes and they provide a higher exhaust gas flow rate, what results in less exhaust back pressure, improved efficiency and lower exhaust gas temperature, which additionally relieves your turbochargers.

Also ideal for performance-increased vehicles.
In addition, a sound plus (sound change) is noticeable after fitting these downpipes. Especially in combination with a sports exhaust system or e.g. our Bull-X front silencer replacement pipes for RS6/ RS7 C8/4K.
