Milltek Valved Cat-Back Exhaust - Porsche 991.1 C2S C4S - OE Tips - SSXPO216

Milltek Valved Cat-Back Exhaust for the Porsche 991.1 Carrera S and 4S

This system completes the Milltek 991.1 C2S and C4S lineup. It pairs the Milltek valved rear section with new Milltek side silencers for a full cat-back, so the PSE valves keep their quiet and loud modes while the whole system carries the Milltek tone.
