Center Muffler Bypass Pipe
Center muffler bypass pipe for the Porsche 997.2 GT3 / GT3 RS (2010-2012), a direct replacement for the failure-prone OEM muffler with a talk-pipe design that blends exhaust from both cylinder banks into a smooth, aggressive sound. It adds 10whp and 8.1 Nm of torque with sharper throttle response, saves 4.5 kg from the rear of the car, and retains the Sport Mode control button when paired with the factory side mufflers. Built from 14-16ga T304 stainless steel and finished with a simplified two-bolt mount, it includes 4in Deluxe Dual-Style Tips in your choice of polished, carbon fibre, satin black, or titanium.
