Milltek Sport (Audi, RS4 B7, 2006-2008) Sports Cats (200CPSI)

Milltek Sport's high-flow sports catalytic converters for the Audi RS4 (B7), 2006-2008 replace the restrictive factory units with genuinely higher cell-count metal substrate cats, delivering improved flow while retaining meaningful emissions control, unlike a full de-cat pipe. Constructed from T-304 stainless steel throughout for long-term durability.

This version uses a 200 cells-per-square-inch substrate.
