Transform Your Porsche 911 991.2 GT3 4.0L with 200-Cell High-Flow Headers and a Valved Performance Exhaust
Designed specifically for the Porsche 911 991.2 GT3 4.0L, this full performance exhaust system combines 200-cell high-flow catted headers with a valved catback exhaust to improve exhaust flow, reduce restriction and deliver a more aggressive naturally aspirated flat-six sound.
Constructed from high-quality 304 stainless steel, the 200-cell catted headers provide increased exhaust gas flow while retaining high-flow catalytic converters. The valved catback section gives you adjustable sound control, allowing for a more refined exhaust tone when cruising and a louder, sharper GT3 exhaust note when the valves are open.
Professional installation is recommended for correct fitment, exhaust alignment and reliable valve operation. ECU calibration may be recommended depending on vehicle specification and tuning setup.
